| 81 | ELECTRONIC DEVICE WITH AUTOMATIC MODE SWITCHING | US13224180 | 2011-09-01 | US20120023060A1 | 2012-01-26 | Fletcher R. ROTHKOPF |
| An electronic device for predicting or anticipating a user's operational desires. The electronic device is ready to perform the anticipated function without input from the user by using sensors to sense environmental attributes. The sensors can include an ambient light sensor, a force sensor, a temperature sensor, an ambient noise sensor, and a motion sensor. The electronic device also includes a control mechanism for switching between modes for the device. | ||||||
| 82 | LIGHT ACTIVATED HOLD SWITCH | US13012638 | 2011-01-24 | US20110116201A1 | 2011-05-19 | Fletcher R. Rothkopf |
| An automatic hold switch is disclosed. The automatic hold switch provides a means for automatically switching a hold feature on and off. When the hold feature is on, one or more input devices of a portable electronic device are disabled or prevented from providing input signals. When the hold feature is off, one or more input devices of a portable electronic device are enabled or allowed to provide input signals. Because the user no longer has to manually control the hold feature, the number of actions that need to be taken by the user is reduced. In one example, the automatic hold switch is embodied with light sensors that detect when the device is in a dark environment and when the device is in a light environment. A dark environment indicates to the portable electronic device that the user wishes not to input and therefore the hold feature is turned on. A lighted environment indicates to the portable electronic device that the user wishes to input and therefore the hold feature is turned off. | ||||||
| 83 | Drive mechanism for a down draft vent system | US11606665 | 2006-11-29 | US20070137636A1 | 2007-06-21 | Boris Mack |
| The invention relates to a drive mechanism for a down draft vent system (8) comprising a retractable down draft vent screen (10) which can be moved between an extended and a retracted position by means of a drive motor (3). The drive mechanism (1) is characterised in that the drive motor (3) is a synchronous motor with a reversing circuit (31, 32, 7) for load-dependent reversal of the driving direction. The present invention can thus provide a safety function against jamming of objects since the drive motor (3) reverses automatically when the load is fairly large. | ||||||

| 87 | Method and system for detecting an object caught in the path of an automotive window using a piezoelectric torque sensing device | US09391298 | 1999-09-07 | US06452351B1 | 2002-09-17 | Charles Hopson; Timothy Davies; Joseph Tyckowski; Christos Kyrtsos; Francois Breynaert; Pascal Bonduel |
| A method and system for detecting the presence of an object caught between an automotive window and its respective frame includes a sensor mounted on a drive motor that drives a regulator to move the window upward and downward. The sensor senses a resistive torque applied against the regulator and generates a signal having a value proportional to the amount of resistive torque sensed. The signal is transmitted to a control circuit which then determines whether or not an object is caught between the window and its respective frame. | ||||||
| 88 | Power window device with safety device | US898004 | 1997-07-25 | US5832664A | 1998-11-10 | Keiichi Tajima; Hitoshi Takeda; Toru Nakayama |
| A safety control power window device which reliably detects nipping of a finger by a window and sash and which is little influenced by variations of motor characteristics of the motor used as a drive source of the power window device. The window position and a thrust pressure acting on the rotary shaft of the motor providing the force for opening and closing the window are detected. Reference pressures for detecting nipping are set according to the window position detected. By comparing the detected pressure and the reference pressures, nipping by the window is detected. Since nipping and the window position are not detected using the drive current of the motor, accurate safety control is realized, eliminating influences caused by variations of the characteristics of the motor. | ||||||
| 89 | Thrust detecting device of a linear actuator | US569693 | 1995-12-08 | US5760357A | 1998-06-02 | Kenichiro Nakamura; Toshio Mitsuyama; Makoto Kishida |
| A device for detecting a change in the thrust load acting on the actuating rod of a linear actuator. The thrust detecting device includes a pinion which converts and enlarges an axial linear displacement of a rotating drive screw shaft caused by a change in the load on an actuating rod driven by the screw shaft into an angular displacement of a vertical shaft of the pinion. A circular scale plate is attached to the vertical shaft of the pinion and serves to indicate a preset value for the load change to be detected. A pair of striker plates each having a pointer effective to select a preset value on the circular scale plate and a striker effective to activate a corresponding limit switch are attached to the circular scale plate. | ||||||

| A regulator for a power window having a safety function for preventing an object from being caught in a closing power window includes a driving unit for raising and lowering the window glass of a vehicle and a driven unit which receives power from the driving unit. When frictional resistance corresponding to relative displacement between the driving and driven units is less than a fixed value during descent of the window glass and exceeds this fixed during ascent of the window glass, the ascending window glass is reversed and made to descend. When the amount of an increase in current to the driving unit during ascent of the window glass increases in a case where the sliding resistance has exceeded a fixed value even once during descent of the window glass, the ascending window glass is reversed and made to descend. | ||||||
| 91 | Rotating paddle bin level indicator | US758753 | 1991-09-12 | US5164555A | 1992-11-17 | Ronald G. Brenton |
| Apparatus for indicating the level of flowable material in a storage bin that includes a motor mounted within a protective enclosure and coupled by a shaft and clutch arrangement to a paddle disposed within the bin to engage material therewithin. When the material reaches the level of the paddle, drag on the paddle causes the motor to rotate within the enclosure against the force of an adjustable spring to activate switches disposed within the enclosure for indicating material level. The switches also remove power from the motor and apply power to an electrical resistance heater to warm the enclosure and help prevent condensation at low external ambient temperature. The paddle is constructed to enhance drag when used in conjunction with low-density materials. | ||||||
| 92 | Automatic door protective reversing switch with worm gear | US542663 | 1990-06-26 | US5063316A | 1991-11-05 | C. E-Ming |
| An automatic door protective device for returning an overhead door to the open position when it encounters an obstacle as it is closing. The protective device of this invention includes a motor having an output shaft and a driving gear mounted on the shaft. A driven gear is in mesh with the driving gear mounted on a gear shaft which also mounts a worm. A worm wheel is in mesh with the worm which is mounted on a worm wheel shaft, which also mounts a pulley that raises and lowers the door in response to rotation of the output shaft to the motor. The end of the gear shaft is spaced away from a copper leaf spring, and an electrical contact is also provided spaced away from the leaf spring. The spring and the contact are part of an electrical circuit with a signal controller coupled to the motor. When the door encounters an obstacle and the pulley ceases rotation, the torque of the motor causes the gear shaft to displace axially as the worm moves along the worm wheel teeth. The end of the gear shaft forces the leaf spring into electrical contact with the contact, and this completes the circuit to the signal controller, which causes the motor to immediately reverse its direction of rotation of the output shaft. | ||||||
| 93 | Contact link for flight controls of aerodynes | US261438 | 1988-10-24 | US4924043A | 1990-05-08 | Jacques A. Aubry; Andre Guillem |
| Contact link for flight controls of aerodynes, especially helicopters. The link comprises a rod (2) mounted axially slideably over a limited stroke under tension and under compression in a body (1). A leaf spring (35) subjected to compressive buckling prestress is accommodated in a recess (27) of the rod (2) between two supports (36, 37) pushed against stops of the rod (2) and stops of the body (1). Under any axial tensile or compressive force higher than the prestress of the leaf spring (35), one of the supports (36, 37) is brought nearer to the other, so that the leaf spring (35) works by buckling, and its central part increases its deflection to an extent amplified in relation to the axial stroke of the rod in the body and shifts radially a movable contact member (55) actuating an electrical contactor (45) fastened in the recess (27) of the rod (2). The contact link is used for equipping flight controls for cutting in or cutting out an automatic pilot. | ||||||
| 94 | Overload detection mechanism for motor-driven linear actuator | US316729 | 1989-02-28 | US4910419A | 1990-03-20 | Shuji Hayashi; Kenichiro Nakamura |
| In a linear actuator comprising a motor-driven screw shaft, an overload detection mechanism comprises a pair of cup-shaped spring seats with substantially cylindrical portions. The spring seats are mounted at one end of the screw shaft by a pair of bearings and have a spring therebetween under a predetermined preload. Limit switches are provided for detecting overload on the screw shaft as a result of axial movement of the spring seats. The cylindrical portions of the cup-shaped spring seats serve as strikers for said limit switch means. | ||||||
| 95 | Overload protection for DC motor-driven linear actuator | US091827 | 1987-09-01 | US4763219A | 1988-08-09 | Kenichiro Nakamura |
| A permanent magnet DC motor-driven linear actuator has a screw shaft supported against axial movement by a compressed spring. Excess thrust in one direction causes the shaft to move axially to open a first momentary switch, and excess thrust in the opposite direction similarly opens a second momentary switch. The switches are connected electrically in series with each other and with the motor, and enable the motor to stop whenever a mechanical overload is encountered regardless of the position of the actuator operating rod. Diodes connected across the switches in opposite directions allow reversal of the motor by reversing polarity of the DC supply, even when a switch is held open. In two of the embodiments of the invention, the swithes are double-throw switches, and additional diodes are connected from the normally open contacts of the switches to the opposite terminal of the motor to provide dynamic braking. | ||||||
| 96 | Rotating paddle bin level indicator | US889699 | 1986-07-28 | US4695685A | 1987-09-22 | Phillip P. Fleckenstein; Norman F. Marsh |
| Apparatus for indicating the level of flowable material in a storage bin comprising a motor mounted within a protective enclosure and coupled by a shaft to a paddle disposed within the bin to engage material contained therein. When the material reaches the level of the paddle, drag on the paddle causes the motor to rotate within the enclosure and thereby to activate switches disposed within the enclosure for indicating material level. A spring is mounted between the enclosure and the motor such that the spring urges the motor to both the switch-activating and the switch-deactivating positions in turn, and must be urged over center to permit motion of the motor in either direction between such positions. | ||||||
