US10634705B2 Method for determining the current consumption of an active load, for example a processing unit, and associated electronic device
A first resistor and a second resistor are coupled in series between a voltage source and an active load. When the current drawn by the active load exceeds a current threshold corresponding to a maximum admissible voltage drop across the first resistor, a stabilization current is delivered to the node common to the series coupled first and second resistors in such a way as to stabilize the voltage on the terminals of the active load at a threshold value. In the presence of such a current in excess of the current threshold, the current consumed by the active load is measured from the voltage drop across the second resistor. Conversely, if the current is less than the current threshold, the current consumed by the active load is measured from the voltage drop across the first resistor.

A device for moving a movable furniture part, including a force accumulator for causing the movable furniture part to be put in the opening direction of the movable furniture part, and wherein the device has a locking assembly for locking a tensioned position of the force accumulator, in which the force accumulator is charged for the opening movement of the furniture part. The tensioned position of the force accumulator is unlockable by displacing an activator element that interacts with the locking assembly. The locking assembly includes a pivotably mounted locking member, and the activator element and the locking member are mutually adapted in such a manner that, for unlocking the tensioned position of the force accumulator, the activator element carries out a linear repositioning movement and comes to bear on the locking member in such a manner that the locking member is subjected to a pivoting movement, or vice versa.
US10633888B1 Control switch connection apparatus
The present invention relates to a method that allows a CSCA to enable an iFOB key system once it is turned on by pressing a function button. When the function button is released, the iFOB key system is turned off. The iFOB key system includes the ERFTS, so when the iFOB key system is turned on/off, the ERFTS is also turned on/off. The embodiment of the CSCA has a double-action switch, a triple-action switch, a timer, a timer circuit and all of the circuitries that are associated with an iFOB key. The CSCA controls the length of time that current is allowed to flow from a battery source to an iFOB key system; it is this type of control that prevents an ERFTS and a customer's property from being compromised. The iFOB key system is always in the off position until it is turned on.
