摘要： A thermal sensing system includes a one-piece clip formed of a thermally conductive material. The clip includes a flat, substantially enclosed portion with tabs extending upward from it for connecting the clip to a printed circuit board. The clip also includes a contact portion that is configured to contact a thermally emitting object along a substantial portion of its surface. The thermal sensing system also includes a thermistor. The thermistor may be mounted to the printed circuit board or directly mounted to the clip. Heat is transferred from the thermal object to the thermistor via the clip. This system may be used in various arrangements in which temperature of an object is monitored or maintained within a given range. For example, the system may be used with a rechargeable mouse to monitor the temperature of the replaceable battery during charging and discontinue charging should the temperature reach a predetermined limit.

摘要： Capacitive proximity sensing is carried out by detecting a relative change in the capacitance of a “scoop” capacitor formed by a conductor and a surrounding ground plane. The conductor may be a plate provided in the form of an adhesive label printed with conductive ink. Charge is transferred between the “scoop” capacitor and a relatively large “bucket” capacitor, and a voltage of the bucket capacitor is applied to an input threshold switch. A state transition (e.g., from low to high, or high to low) of the input threshold switch is detected and a value (TouchVal) indicative of a number of cycles of charge transfer required to reach the state transition is determined. The presence or absence of an object or body portion in close proximity to or contact with a device can be determined by comparing TouchVal with a predetermined threshold value (TouchOff). TouchOff can be adjusted to take into account environmentally induced (non-touch related) changes in the capacitance of the scoop capacitor. Power management is provided in a user operated data input device utilizing proximity sensing and switching between three or more power states. Switching between the power states occurs based upon the presence or absence of input activity, and an operation instrumentality (e.g., a hand) in close proximity to or contact with the device. In an optical surface tracking cursor control device embodiment, switching to and from a BEACON state, which provides a reduced flash rate of a surface illuminating light source, is carried out based upon a detected presence or absence of a trackable surface.
