摘要： Circuits for self-powered image sensors are provided. In some embodiments, an image sensor is provided, the image comprising: a plurality of pixels, each of the plurality of pixels comprising: a photodiode having an anode and a cathode connected to a ground voltage; a first transistor having: a first input connected to the anode of the photodiode; a first output connected to a reset bus; and a first control configured to receive a discharge signal; and a second transistor having: a second input connected to the anode of the photodiode; a second output connected to a pixel output bus; and a second control configured to receive a select signal; and a third transistor having: a third input coupled to each first output via the reset bus; a third output configured to be coupled to an energy storage device; and a third control configured to receive an energy harvest signal.

摘要： A heater unit is adapted to determine if a humidification chamber thermally coupled to a hot plate of the heater unit is effectively dry based on determining a thermal response of a hot plate of the heater unit. Also, the activation period during which the hot plate is being heated is adjusted toward an optimum period by adjusting the energization or power level to the heater element thereof in relation to the duration of a prior activation period. Further, the air flow rate of gas through the humidification chamber may be estimated based on a temperature of the hot plate determined in predetermined relationship to the beginning of an activation period.

摘要： Circuits for self-powered image sensors are provided. In some embodiments, an image sensor is provided, the image comprising: a plurality of pixels, each of the plurality of pixels comprising: a photodiode having an anode and a cathode connected to a constant voltage level; a first transistor having: a first input connected to the anode of the photodiode; a first output connected to a reset bus; and a first control configured to receive a discharge signal; and a second transistor having: a second input connected to the anode of the photodiode; a second output connected to a pixel output bus; and a second control configured to receive a select signal; and a third transistor having: a third input coupled to each first output via the reset bus; a third output configured to be coupled to an energy storage device; and a third control configured to receive an energy harvest signal.

摘要： Method and apparatus for providing controllable power to the load via AC-line power source where load is less than minimal required for proper operation of said source. In one example LED lamp connected to AC power source via conventional triac-based dimmer uses less power than minimum required for proper operation of said dimmer. In another example LED lamp connected to AC power source via device known as electronic transformer uses less power than required for proper operation of said electronic transformer.
