Abstract: A programmable arbitrary sequence direct memory access (DMA) controller accesses sequentially addressed memory locations (source or destination) using address pointer registers. Each sequentially addressed memory location containing an indirect memory address is stored in an address latch and used to access the actual non-sequential memory location to be accessed by the DMA transfer.

Abstract: A smoke detection sensor ion chamber has a capacitance and a change in the permittivity of that capacitance dielectric (ionized air in the chamber) may be used to detect the presence of smoke therein. Smoke from typical fires is mainly composed of unburned carbon that has diffused in the surrounding air and rises with the heat of the fire. The permittivity of the carbon particles is about 10 to 15 times the permittivity of clean air. The addition of the carbon particles into the air in the ion chamber changes in the permittivity thereof that is large enough to measure by measuring a change in capacitance of the ion chamber.

Abstract: A capacitive flex sensor comprises a first capacitor plate disposed on a first surface of a flexible insulated substrate and a second capacitor plate is provided on a second surface of the flexible substrate. The flexible substrate is adapted to be a compressible and stretchable dielectric between the first and second capacitor plates. A plurality of these capacitive flex sensors are positioned on the flexible substrate, e.g., a glove, that may be adapted to conform to a body part having flexure points. A preferred body part is a hand/fingers and the capacitive flex sensors may be located proximate to movable joints of the hand/fingers. Movement (flexing) of a joint may cause the physical structure of the capacitive flex sensor to be depressed or deformed. This causes the dielectric thickness and/or plate area to change, thus changing the capacitance value of the flex sensor located proximate to the joint being flexed.

Abstract: A vehicle movement tracking system that employs floor mats having ridges for generating location information in the form of modulated vibrations, detectable with an accelerometer. Two sensors are in a wheel of a vehicle. One sensor senses wheel rotation, and the other sensor senses vertical acceleration. The vehicle passes over a floor mat comprising vertically elevated ridges thereon that code the mat and thereby indicate the location at which the mat is at. When the vehicle travels over this mat the vertical acceleration sensor in the wheel detects the vertically elevated ridges and the wheel rotation sensor detects the distance between the vertically elevated ridges. In combination these two sensors are used to create a location word that denotes the mat over which the vehicle passes over. The location word is stored in non-volatile memory and later uploaded to a location collection station.

Abstract: A vehicle movement tracking system that employs floor mats for generating location information using magnetic stripes, detectable with a magnetic sensor in a wheel of the vehicle. Two sensors are in a wheel of a vehicle. One sensor senses wheel rotation, and the other sensor senses a magnetic. The vehicle passes over a floor mat comprising magnetic stripes thereon that code the mat and thereby indicate the location at which the mat is at. When the vehicle travels over this mat, the magnetic sensor in the wheel detects the magnetic stripes and the wheel rotation sensor detects the distance between the magnetic stripes. In combination, these two sensors are used to create a location word that denotes the mat over which the vehicle passes over. The location word is stored in non-volatile memory and later uploaded to a location collection station.

Abstract: A smoke detection sensor ion chamber has a leakage current that is dependent upon the permittivity of the ionized gas (air) in the chamber. Smoke from typical fires is mainly composed of unburned carbon that has diffused in the surrounding air and rises with the heat of the fire. The permittivity of the carbon particles is about 10 to 15 times the permittivity of clean air. The addition of the carbon particles into the air in the ion chamber changes the permittivity thereof that is large enough to detect by measuring a change in the leakage current of the ion chamber.

Abstract: A combination of capacitive, mutual capacitive, and inductive proximity and touch sensing is used to detect the presence and nature of nearby objects to a wireless device. When the proximity of metal or a user is sensed the output power of a Wi-Fi module in the device is reduced so as to prevent harm to the user and/or the Wi-Fi transmitter amplifier circuits. Inductive sensors located at the four corners of the wireless device are used to detect metal, and capacitive sensors are used to detect a capacitance change or shift due to the presence of a user's hand, body or metal. In addition, the capacitive sensors may be located at the four corners of the device and can measure changes in the mutual capacitance coupling between these capacitive sensors.
