| 162 | Laser bow sight apparatus | US44447 | 1998-03-19 | US6073352A | 2000-06-13 | Blair J. Zykan; Jeremy G. Dunne |
| A laser rangefinder bow sight adapted for use preferably with a conventional multi-pin bow sight having a frame and a plurality of sighting pins adjustably positioned on said frame. The laser rangefinder has a housing removably fastened to the bow sight frame. The housing supports a laser transmit section, a laser receive section, a precision timing section and a central processing unit (CPU) for measuring distance to a target coupled to an LCD display. The CPU also provides outputs to a plurality of range window indicator lights which are preferably LEDs. The indicator lights may be externally mounted to the bow sight pins or mounted within the rangefinder housing. In the latter case, a plurality of optical fibers are connected to the distance window lights in the housing. Each of the sighting pins is optically coupled to a separate one of the plurality of distance window lights via one of the optical fibers. The rangefinder is actuated via a remote trigger switch connected through the power supply in the housing to each of the sections. When the rangefinder is triggered, the CPU determines the target distance and activates one or more of the distance window LEDs for the range window or windows closest to the measured distance. Light is then transmitted via the optical fibers to the sighting pins, thus illuminating the one or two sighting pins corresponding to the measured distance. The display is held for a predetermined period of time or until the archer actuates the remote switch to take another distance measurement. | ||||||

| 165 | Sonar depth finder with relative depth LCD display | US580914 | 1984-02-16 | US4644512A | 1987-02-17 | Henry G. Grilk |
| A computer system is proposed for finding and displaying the depth and depth related values of an object in an aquatic environment in which and LCD display is subdivided into segments each representing a fraction of the total depth range in which the system is operating as well as a fraction of the transit time for the transmission of pulses within the depth range. Each segment is addressed and activated in response to the presence of a receiver output in the microprocessor for a given number of consecutive time-scans, thus providing a quasi-analog visual display of depth on the array of the segmented scale. | ||||||
| 166 | Talking depth sounder | US645491 | 1984-08-29 | US4616350A | 1986-10-07 | Robert K. Tendler |
| Apparatus is provided for adapting an analog depth sounder for the calling out of the depth at regular time intervals. In one embodiment, a self-contained adapter module is mounted to the face of the depth sounder so as to cover the depth sounder display, with the module including a transparent plate carrying a detector array and with electronics and speaker carried at the center of the array. In this embodiment, the detectors are arranged in thin radially extending lines to permit accommodation to displays of different diameter. Alternatively, small detectors are arranged along a circle having a diameter which overlies at least a portion of the orbiting radiating element which radiates along a considerable length. This alternative array configuration also accommodates a range of display diameters. As a further alternative, to accommodate different diameter displays, the thin line detectors may be replaced with radially extending light pipes with detectors at their ends. The transparent plate with almost invisible detection apparatus permits viewing of the depth sounder display through the plate so that visual as well as audible readout may be achieved. Electronics is provided to decode the angular position of the orbiting element of the depth sounder at the time the element is actuated to provide a digital number representing depth. This number is then used in generating its speech equivalent through a standard speech synthesizer and loudspeaker. The electronics may include a number of different ROMS or different sections of a single ROM to provide for scale adjustment. Alternatively, a variable rate clock may be used to adjust for scale. Alternative embodiments include sensing the time difference between pulses of electromagnetic radiation from the depth sounder to establish depth, with the signals being available outside the depth sounder case. In each embodiment, signals which activate the speech synthesizer may be used to drive a digital display for improved filtering against spurious signals. | ||||||

| An ultrasonic detector for roadway vehicles comprises an array of electroacoustic transducers mounted on the rear of the vehicle. The transducers are sequentially driven by a transmitter circuit to transmit a pulsed, laterally shifting ultrasonic energy toward an object located behind the vehicle in one of plural regions defined by partially overlapped directivity patterns of adjacent transducers. A receiver circuit is coupled to the transducer array to receive echos returning from the object during the interval between successive beam transmissions. A logic circuit detects the lateral position of and the distance to the object for giving relevant indications on a display unit, the audible tone being variable depending on object distance. An audible warning device is optional. | ||||||

| 170 | Graphic recording system | US735265 | 1976-10-26 | US4096484A | 1978-06-20 | Radford G. Ferre; Brent Rudy Miller |
| A graphic recording system for use with a multiple channel underwater sonar system. The recording system includes a plurality of memories, each for storing information received over a different channel of the sonar system. One or more channels may carry side scan sonar information, while another may carry sub-bottom sonar information, etc. The information from the channels is received and stored in the memories simultaneously. The recording system further includes a graphic line recorder which is responsive to the receipt of a sequence of signals for producing on chart paper a line trace representation of the signals. A control unit controls the storage of information in and retrieval of information from the memories and application of the information to the graphic line recorder in such a manner that the information may be applied to the recorder in various sequences and at various rates. This allows the production of graphic displays of information from selected information channels, and having selectable distance or time scale factors. The recording system also includes data inverting apparatus for selectively inverting information supplied to the recorder so that either so-called positive or negative traces can be produced. | ||||||

| A depth sounder having a dial that includes a viewing area, a plurality of indicia surrounding the viewing area, and a flasher that sweeps the viewing area and flashes adjacent to an indicium to indicate the depth sounded, the dial being generally opaque with transparent or translucent indicia so that light from the flasher will illuminate at least some of the indicia in the vicinity of the indicium indicating the depth sounded. | ||||||
| 172 | Circuit for water depth meter | US3764962D | 1972-01-10 | US3764962A | 1973-10-09 | BARTEL C |
| A depth meter for use in water, which has a rotating disc carrying a light emitting diode that lights up to give depth indications. The rotating disc also carries a magnet which is used to generate a signal to initiate transmission of a high frequency signal through a crystal. The crystal receives any returned signal reflected from the bottom or an object in the water. The reflected signal is amplified, and a pulse discrimination circuit is used to determine if the amplified signal is acceptable. An acceptable signal trips a power circuit to a light emitting diode to indicate the depth of the bottom or object causing the reflected signal.

| In a method for checking a first ultrasonic sensor of a motor vehicle for an occlusion, a measuring signal of the first ultrasonic sensor is acquired by an evaluation unit, and from the measuring signal, a decay time of a natural oscillation of the diaphragm of the first ultrasonic sensor, brought about by an excitation pulse, is ascertained. From the measuring signal of either the first ultrasonic sensor or a second ultrasonic sensor, an echo produced by an object located in a sensing range of the first ultrasonic sensor is ascertained, and a distance value of the object is determined on the basis of the echo. An occlusion is signaled if the decay time is less than a predetermined threshold value which would be exceeded if ice and/or dirt were to adhere directly to the diaphragm, and if the distance value is less than a predetermined maximum value. | ||||||
