International Classification:

G01N 27/416

US Classification:

324430, 324426, 324427, 324428, 324429

Abstract:

A circuit that indicates an impedance of a battery dielectric includes a signal generator module that flows a first current from a ground to a first terminal of a battery. A sensor circuit generates a signal based on a second current that flows from a second terminal of the battery through a resistance to ground. The second current includes the first current and a third current that flows to ground via an impedance presented by a battery dielectric housing. A signal conversion module generates an output signal based on the signal. The output signal represents the impedance presented by the battery dielectric housing.

Abstract:

A new lighting control utilizes common infrared remote controllers such as the “universal remote controller” available for controlling TV, VCR and other audio/video components and devices in home use. The new infrared receiver controllers incorporate receivers that recognize many control protocols, have the ability to learn and respond to one protocol field-assigned to a particular control device and to simultaneously ignore messages directed to other control system components. A particular receiver is able to accept different communication protocols generated under audio/video maker-specific presets. Most audio/video makers have a proprietary code format which differs from others in carrier frequency used, code type (bi-phase or pulse distance modulation), length of message, timing of data bits and start sequence, repetition format and rate and number of bits/message. The receiver and associated microprocessor recognizes a particular characteristic of an incoming communication and by comparison with a plurality of images in memory locks on to a particular code and screens out other codes stored in memory which may be used for other devices and components controlled by the infrared remote controller. In this manner, a particular light or plurality of lights may be controlled by the same “universal remote controller” that controls the TV, VCR and other devices in the same room or vicinity.
