  • Publication number: 20080135467
    Abstract: A filtration device is provided that includes a filter component and an additive component. The filter component includes concentrically arranged filtering elements disposed in a filter-in-filter configuration. The additive component includes at least one additive material that is introduced into a working fluid to be filtered. The filter component and additive component provide an assembly for a filtration system that would filter a variety of working fluids. The filter component and additive component provides an assembly that can filter fluids more efficiently. As a result, fluids may enjoy, for example, extended drainage intervals and thereby reduce component wear.

  • Patent number: 7362372
    Abstract: A video surveillance camera comprising an image sensor, first housing, second housing, electronic circuit, and thermal barrier. The image sensor is located in the first housing, and the electronic circuit is located in the second housing. The thermal barrier has first and second sides with the first side located adjacent to the first housing and the second side located adjacent to the second housing. The image sensor and other electronics, such as the processor board associated with the image sensor or the camera power supply, are located in separate housings or chambers that are separated and insulated from each other by a thermal barrier, thereby minimizing the heat generated by the processor electronics or power supply from being transferred to the area of the image sensor.

  • Publication number: 20040114681
    Abstract: In a system that uses equalization signaling to determine at least one equalization parameter representative of at least one property of a channel, a signal is received on the channel. A rate of change of the at least one property of the channel is estimated. Based on the rate of change of the at least one property of the channel, the equalization signaling is adjusted.

  • Publication number: 20040057507
    Abstract: A first device (102/104) receives a first message (300) from a second device (104/102) over a communication link (106). The first device also receives a first transmit power level (202/212) by which the first message was transmitted and a first interference level (204/208) as perceived by the second device. The first device calculates at least one transmission parameter by which a second message will be transmitted to the second device based on the first transmit power level and the first interference level.

  • Patent number: 6593883
    Abstract: A first signal and a second signal are detected. The first and second signals are transmitted according to a timing pattern. An arrival time is identified for the first and second signals. Based on the timing pattern and the estimated arrival times of the first and second signals, a set of parameters is derived that characterize a timing relationship between a first device (100) and a second device (200).

  • Patent number: 6515623
    Abstract: A first device (100) transmits a first signal to a second device (300) at a first time. A third device (110) detects a second signal from the second device (300) at a second time. The second signal was transmitted in response to detection of the first signal. Based on the first and second times, a sum of a first propagation delay (200) and a second propagation delay (210) is estimated. The first propagation delay (200) is between the first device (100) and the second device (300), and the second propagation delay (210) is between the second device (300) and the third device (110). The sum of the first and second propagation delays (200, 210) is then used to estimate a location of the second device (300).
