Abstract: The present invention discloses a method and apparatus for reducing the power required by an integrated services hub supporting a plurality of telephone circuits, comprising offsetting ringing of each of the plurality of telephone circuits such that all the telephone circuits do not ring simultaneously. The step of offsetting ringing of each of the plurality of telephone circuits preferably further comprises providing each telephone circuit with a ring cadence comprising a ringing interval and a non-ringing interval and defining a starting point for the ringing interval within each telephone circuit's ring cadence such that the starting point for the ringing interval for at least one telephone circuit falls substantially outside the ringing intervals of the remaining telephone circuits.

Abstract: The present invention discloses a method for reducing battery power consumed by an integrated services hub supporting a plurality of telephone lines. The status of power to the integrated services hub is monitored, and upon detecting a failure of primary power, each of the telephone lines is polled to detect an off-hook condition. The status of power to the integrated services hub is monitored while polling, and the polling is stopped upon detecting a return of primary power to the integrated services hub or upon detecting an off-hook condition in one of the telephone lines. Polling is performed by placing one of the telephone lines in a standby state and the remaining telephone lines in a disabled state and monitoring the telephone line in standby state for a predetermined amount of time to detect an off-hook condition. After the predetermined amount of time has lapsed, the monitored telephone line is changed from standby state to disabled state, and the next of the plurality of telephone lines is placed in a standby state, while any remaining telephone lines remain a disabled state. This polling sequence is repeated during active polling.

Abstract translation: 本发明公开了一种减少由支持多条电话线路的综合业务集线器所消耗电力的方法。 对集成服务集线器的电力状态进行监控，一旦检测到主电源故障，则轮询每条电话线以检测摘机状态。 在轮询时监视集成服务集线器的电力状态，并且在检测到集成服务集线器的主电源返回或者在检测到其中一条电​​话线路中的摘机状态时停止轮询。 轮询是通过将一条电话线路置于待机状态，其余电话线路处于禁用状态，并且在待机状态下监视电话线路预定的时间量来检测摘机状态来执行轮询。 经过预定的时间后，被监控的电话线路将从待机状态变为禁用状态，并且将多个电话线中的下一个电话线置于待机状态，而任何剩余的电话线路仍然处于禁用状态。 在主动轮询期间重复此轮询序列。

Abstract: A method and system are provided for reliably detecting localized birefringence defects of an object such as an optical media substrate in a dynamic local birefringence field created during cooling of the optical media substrate at an inspection station. A birefringence digital filter filters out high frequency defect data while eliminating background birefringence data in a digital image created by a camera adapted to respond to the birefringence of the optical media substrate under control of a computer. Resulting filtered high frequency defect data is then processed to determine the localized birefringence defects in real-time. In one embodiment, the birefringence digital filter includes an addressable storage device such as a PROM which stores a lookup table which is able to produce filtered data in real-time at a data rate in excess of 8 million pixels per second. In another embodiment, a finite impulse response (FIR) filter, including registered multiplier-adders may be used to calculate or obtain filtered data at a higher rate (i.e. 10 million pixels per second). The filtered data may be post processed to accomplish gain and offset correction as well as to impose nonlinear characteristics on the output data if desired to implement a data squelch. The data squelch can reduce undesirable noise generated as an artifact of the filtering process.

Abstract: The intensity of each lamp which illuminates an object at an inspection station is controlled by controlling driving voltage applied to a power supply which supplies electrical power to the lamp. A phototransistor is used to sense the intensity of the lamp through an optical fiber. The sensor is followed by a digitally-controlled, variable gain circuit whose output is fed to an A-D converter. A microprocessor analyzes the digital signal from the A-D converter and corrects the driving voltage to the power supply to keep the intensity output of the lamp constant, as seen by a camera of a machine vision system. In this way, feedback corrects for a degraded lamp output due to aging. Preferably, the control of the level of lamp intensity can be changed from a remote system console of the machine vision system to reduce the need for access to internal parts, thereby reducing the probability that human error may cause a malfunction. The method and system of the present invention are particularly useful for inspection of digital versatile discs (DVD's) where the illumination must be changed. Also, the method and system are particularly useful in automated production lines where both audio and DVD discs are inspected. The lamp intensity control method and system can quickly change intensities for the appropriate discs.
