摘要： A method is disclosed for determining when a frequency-modulated expected information signal resides at a predetermined channel. The method is based on determining a value based on the frequency deviation of the received signal, and then comparing the value with a threshold based on the expected information signal. The method is particularly well-suited for use as a squelch detector in digital FM radios.

摘要： 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.

摘要： 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).

摘要： An improved method and apparatus for synchronizing a receiver oscillator with a transmitter oscillator is provided. The receiver is arranged with a counter driven by the receiver oscillator; and the transmitter is arranged with a counter driven by the transmitter oscillator. The transmitter sends a start signal to the receiver and simultaneously records the current reading of its counter. Later, the transmitter sends a stop signal to the receiver and simultaneously records the current reading of its counter. The transmitter then computes the elapsed count, and sends this value to the receiver as the "transmitter reading". Upon receipt of the start signal, the receiver records the current reading of its counter. Later, upon receipt of the stop signal, the receiver records the current reading of its counter, and then computes the elapsed count. Upon receipt of the "transmitter reading", the receiver is then able to determine the error of its own oscillator relative to that of the transmitter site oscillator as: ##EQU1## where A and B are predetermined constants which may be used to normalize the receiver and transmitter counter speeds to each other or to a third set of units. The transmitter then warps its own oscillator based on the calculated error. In an alternate embodiment, the transmitter resets its counter to zero upon sending the first start signal; and the receiver resets its counter to zero upon receipt of this signal.

摘要： A circuit arrangement automatically detects and corrects received data in an FSK signalling scheme wherein FSK data symbols are represented by a grey code-like numbering system and a predetermined word sync pattern leads each data transmission. The arrangement includes a memory (226) for prestoring data representative of the word sync pattern, a comparator (224) for comparing the prestored word sync pattern with the received data, an error detection circuit (228-252) for determining if the grey code-like numbering system has been transposed, and an error correcting circuit (220) for automatically correcting the transposition in the data.

摘要： 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.

摘要： An upper endcap of a fuel filter cartridge includes a skirt, an axially extending pin surrounded by the skirt, and a plurality of ribs that define fluid flow channels leading to the pin. The pin is extendable through an axially facing fuel inlet opening at the upper end of a standpipe for actuating a valve to an open position allowing fuel to flow through the axially facing inlet opening and into the standpipe. The valve can include a hole that receives the pin therein to help stabilize the valve when the valve is actuated open.
