A package deposit enclosure designed for public use is powered by an efficient storage battery and photovoltaic cell array. These unique features allow the package deposit enclosure to be placed in locations where no power is available, but where there is frequent human traffic. Sensing and wireless data communication features allow the unit to be emptied less often than typical package delivery enclosures. Wireless communication also allows users' access to real-time information. On board power enables other functions, such as lighting and audio, to enhance device functionality.

A circuit device includes an A/D conversion unit, a processing unit that performs a temperature compensation process of an oscillation frequency based on temperature detection data and outputs frequency control data of the oscillation frequency, a D/A conversion unit, and an oscillation circuit. The D/A conversion unit (area DAC) is disposed on a first direction DR1 side of the A/D conversion unit (area ADC). When a direction crossing the first direction DR1 is defined as a second direction DR2, the processing unit (area DSPL) is disposed on the second direction DR2 side of the A/D conversion unit and the D/A conversion unit. When a direction opposite to the second direction DR2 is defined as a third direction DR3, the oscillation circuit (area OSC) is disposed on the third direction DR3 side or the first direction DR1 side of the D/A conversion unit.

This disclosure relates to a method of detecting an occupancy state of a living space for controlling an on/off performance of an electrical apparatus. The method comprises using a motion sensor to send wave signal and detect wave signal reflected from a moving human body and using a dual sensitivity detection arrangement including a low sensitivity detection mode and a high sensitivity detection mode respectively performed for identifying the wave signal being a motion signal according to the electrical apparatus being in a turned-off state or in a turned-on state. The dual sensitivity detection arrangement enables the motion sensor to more precisely detect the occupancy state of a living space while minimizing a probability of the electrical apparatus being activated by a noise signal.

A temperature compensated crystal oscillator (TCXO) includes a crystal oscillator and a temperature sensor to provide a sensed temperature. A delay circuit has a selectable delay to delay the frequency compensation based on the sensed temperature. The delay compensates for a difference between when the temperature sensor reflects a change in temperature and when a frequency of a signal supplied by the crystal oscillator is affected by the change in temperature. The delay may be static or dynamic with respect to the current temperature sensed by the temperature sensor.

Techniques and mechanisms for sensing an overlap of an ophthalmic device by an eyelid of a user while the ophthalmic device is disposed in or on an eye of the user. In an embodiment, a circuit, disposed in a sealed enclosure of the ophthalmic device, interacts via an electromagnetic field with a film of tear fluid that is formed on the ophthalmic device. Based on the electromagnetic interaction, an oscillation characteristic of the circuit is evaluated. The oscillation characteristic varies with a resistance that is due in part to an eyelid of the user overlapping at least some portion of the ophthalmic device. Based on the evaluated oscillation characteristic, an amount of the eyelid overlap is determined by circuitry of the ophthalmic device. In another embodiment, the amount of eyelid overlap is used to determine one or more characteristics of gazing by the user's eye.
