Filed:

May 26, 2011

Appl. No.:

13/116438

Joseph Christian Ernest - Woodstock IL, US
Sean Edward Callahan - Elmhurst IL, US

International Classification:

G08B 21/00
G01R 31/14

US Classification:

340650, 340649, 340635

Abstract:

An automatic fault detector momentarily interrupts a provision of operating power to a load having a minimal forward-bias voltage requirement to thereby provide a testing window and then applies a test voltage during this window that is less than the minimal forward-bias voltage requirement to the load and monitors for a power-to-ground fault. By one approach the aforementioned momentarily interruption of power is neither frequent enough nor long enough in duration to substantially impair the provision of power to the load. Accordingly, load performance is not noticeably diminished. One can then responsively prohibit subsequent provision of the operating power to the load. One can then continue to monitor for the power-to-ground fault while continuing to prohibit provision of operating power to the load. If and when the fault disappears, these teachings will then accommodate automatically resuming an ordinary provision of power to the load.

Appl. No.:

10/024797

Inventors:

Lamonte Yarroll - Palatine IL, US
Edward Chen - Palatine IL, US

International Classification:

G06F015/173
H04Q007/20

US Classification:

709/224000, 455/423000

Abstract:

An apparatus and method for tuning voice playback ratio (pbr) to optimize call quality in a packet voice communications system, while taking into account network conditions. The pbr is the ratio of resampling rate to the original sampling rate. The invention also optimizes jitter buffer length (jb) for call quality. Between bursts of speech, the preferred embodiment of the invention optimizes call quality by varying the initial jband the pbr to achieve the best R-factor (R). R is an estimate of customer satisfaction with the quality of a voice call in real time. During bursts of speech, the value of jbis fixed at the beginning of the BOS and the pbr is varied to achieve the best R. The method can be implemented during a burst of speech and between bursts of speech whenever the network conditions change.

International Classification:

G09F 13/04
G09F 13/22

Abstract:

A physically-discrete sign component comprises an internally-electrically-illuminated alphabetic character having a front-facing profile and at least one connecting bar disposed at least substantially horizontally with respect to the front-facing profile of the alphabetic character and at least partially within the front-facing profile of that alphabetic character. By one approach the physically-discrete sign component includes two of the connecting bars. If desired, these two connecting bars are disposed at least substantially parallel to one another. By one approach, a first one of the connecting bars extends partially, but not wholly, above an upper periphery of the aforementioned front-facing profile while the second connecting bar extends partially, but not wholly, below a lower periphery of the front-facing profile. The connecting bars can include a connecting-bar interface configured to physically and electrically interconnect to an adjacent sign component.
