An electronic device for detecting presence includes a housing, an infrared (“IR”) sensor disposed in the housing, and a waveguide included in the housing. The waveguide is configured to collect heat or IR signal emitted by a person from outside of the housing and guide the collected IR signal to the IR sensor. The IR sensor is configured to receive the IR signal via the waveguide and generate a signal in response thereto.

Abstract:
A wearable device includes a capacitive sensor and capacitance sensing and calibration logic operative to determine that component drift for a capacitive sensor cannot be determined based on a capacitance sensed by the capacitive sensor. The capacitance sensing and calibration logic deactivates a drift calibration operation for the capacitive sensor while the capacitive sensor senses the capacitance. The capacitance sensing and calibration logic is further operative to determine that the capacitance sensed by the capacitive sensor is within a detection threshold that indicates that a conductive surface is within proximity of the capacitive sensor. The capacitance sensing and calibration logic can also determine that a wearable device, that includes the capacitive sensor, is in motion based on sensed intermittent changes in the capacitance. Various other methods of operation are disclosed.

In one embodiment a method of operating a mobile device includes sensing either an orientation or a movement of the mobile device, determining a command based on the sensed orientation or sensed movement, sensing a proximity of an object in relation to at least a portion of the mobile device, and executing the command upon the proximity of the object being sensed. In another embodiment, a method of operating a mobile device governs a manner of interaction of the mobile device relative to one or more other mobile devices. In at least some embodiments, at least one of the mobile devices includes an accelerometer and an infrared proximity sensor, and operation of the mobile device is determined based upon signals from those components.
Abstract:
One example disclosed wearable device includes a first housing portion having a conductive section and a non-conductive section. The conductive section is connected to ground. A second housing portion includes a printed circuit board (PCB) with a conductor on the PCB surface positioned beneath the non-conductive section. The conductor on the PCB surface and the conductive section form a capacitor of a capacitive sensor. The wearable device may also include a first adhesive layer between a surface of the non-conductive section of the first housing portion and the PCB surface. A second adhesive layer, coplanar with the first adhesive layer, may be applied between a surface of the conductive section of the first housing portion and the PCB surface. The first adhesive layer and the second adhesive layer form a water tight seal that prevents liquids from penetrating into at least the second housing portion.
Abstract:
An infrared sensing strip includes a substantially linear substrate board, a receiver diode, and a plurality of light emitting diodes (LEDs) linearly aligned along the linear substrate board. Each of the LEDs is operative to transmit in a different direction. The infrared sensing strip utilizes prismatic films arranged to refract light from each of the LEDs in different directions. In one embodiment, the receiver diode is positioned centrally on the linear substrate board, and includes at least four LEDs, with two of each being disposed on either side of the receiver diode. Four prismatic films each cover a respective one of the LEDs and are arranged to refract light from each respective LED in one of four different directions. The small scale of the infrared sensing strip enables various applications including a scroll control, volume control, a heart rate monitor and various transmit and receive features.
