Abstract: An economical three-component snow guard comprising (1) a laminar strap, (2) a snow-stop and (3) a gusseted brace is reinforced and its rigidity and compressive strength greatly improved. At the same time, the resistance to damage due to re-freezing of melted snow, and internal weathering of the brace, is essentially eliminated. The disdavantages of a structurally similar prior artsnow guard are unexpectedly avoided by providing particularly improved structural features. The novel snow guard, formed as a unitary structure of foldable sheet metal less than 2 mm thick can withstand not only the forces exerted by an accumulated snow pack, but also the compressive force of a person's weight exerted in either the down-roof or vertical directions.

Abstract: According to the present invention, a method is provided enabling an analog mode m to dial out while a dial tone is interrupted or stuttered due to at least one un heard message at a Central Office for a subscriber to Call Answer is provided . Call A nswer is an automated voice messaging system which causes the dial tone of a phone lin e connected to the modem, to be either interrupted or stuttered when a message is waiting for the subscriber. Users of the present invention are able to receive o n-line access faster than users of the prior art. The method of the present invention implements a software program within the modem. By comparing the elapsed length of the dial tone with two predetermined time values (a maximum and a minimum), t he method detects the presence and status of the dial tone and informs the modem of the status of the dial tone. Provided that a dial tone is present, whether uninterru pted interrupted or stuttered, the modem proceeds to dial out.

Title: Method and device for recognizing tones and sequences thereof
Inventor: VERREAULT ERIC
IPC: H04N1/327
Filed: 1998-07-03
Granted: 2006-09-19
Abstract: A method for recognizing tones in a signal in a telecommunication transmission uses samples of the signal to determine whether a tone of an expected frequency and wave shape is contained in the signal. If the method accurately predicts the value of the next sample, then a tone of the expected frequency and wave shape has been detected. Another method may be used to recognize sequences of tones comprising intervals with particular frequencies and durations. The method may be applied to the detection of initiation sequences for fax and modem transmissions, for example the ITU-T recommendation T.30 V.21 fax initiation sequence and the ITU-T recommendation V.25 modem transmission preamble. The method may be incorporated in a device for detecting modem or fax transmissions on a line and routing such modem and fax transmissions to a modem/fax relay. Thus the invention can be used with devices which provide voice compression by ensuring that fax and modem transmissions are not corrupted by being passed through the voice compressors.

Title: Cross training exercise device
Inventor: WHAN-TONG JANINE
IPC: A63B21/005
Filed: 1998-11-10
Granted: 2004-01-13
Abstract: An exercise device includes a pair of foot engaging links (30a, 30b). The rearward ends of the foot links are supported by a coupling system (100, 102, 104, 110) for arcuate motion about a closed path of travel, and the forward ends of the foot links travel back and forth along a guide (36). The combination of these two foot link motions permits the users feet to travel along an elliptical path of travel. The inclination or elevation of the guide may be selectively altered to vary inclination of the foot links which in turn changes the nature of the stepping motion experienced by the user. At flatter inclinations of the foot links, the stepping motion may resemble cross country skiing. At progressively greater angles of inclination of the foot links, the stepping motions may simulate walking, jogging, running and climbing. Also, the coupling system may be adjustable to change the length of the closed path of travel of the rear ends of the foot links.

Abstract: An optical channel regulator (46) is provided. The optical channel regulator (46) includes a tapped optical coupler (60) receiving an optical line carrying an optical signal. The tapped optical coupler (60) provides substantially all of the optical signal as an output. An electrically variable optical attenuator (64) receives the output of the tapped optical coupler (60) and attenuates the optical signal responsive to a feedback control signal. A  second tapped optical coupler (66) receives an output of the attenuator (64).  The second coupler (66) provides substantially all of the received optical signal as an output and provides a remaining portion of the optical signal as a tapped output. An optical detector (68) then receives the tapped output and provides an output signal representing the optical signal. A comparator (70) receives the output signal of the optical detector (68) and a reference signal. The comparator (70) compares the output signal and the reference signal and provides the feedback control signal to the attenuator (64) responsive to the comparison. As part of a multi-channel communication system, the regulator is used to adjust the levels of each channel for automatically maintaining channel balance and equalization.
