Title: Interaction of Routing Features in a Telephone System
Inventor: ZAVE PAMELA
IPC: H04M3/54
Filed: 1996-07-30
Abstract: Techniques for analyzing interactions of call routing features in a telephone system and implementing the features. Analysis and implementations are based on the recognition that a customer intends a call routing feature to apply to a telephone number which represents either a subscriber to which a call should be routed or a telephone number to which a call should be routed. From this recognition flow two classes of routing features: telephone features, which apply to telephone numbers representing telephones, and subscriber features, which apply to telephone numbers representing subscribers. How a given feature interacts with other routing features depends upon which of of the two classes it belongs to. Routing features may be implemented by keeping track of a telephone number which functions as a subscriber pointer and of one which functions as a telephone pointer and recursively invoking functions for subscriber and telephone features. The recursive invocations permit forwarding chains of any length. The techniques have also led to the development of a number of new call forwarding and call blocking features.
Patent CA-2183949-A1 (CA)
Inventor: HERZBERGER RICHARD C
IPC: F16K37/00
Filed: 1996-08-22
Abstract: A valve position indicator for on/off valves includes a card having red and green sectors journalled in a housing, and gravity biased to remain stationary during rotation of the housing about a non-vertical axis.  A cover of the housing overlies the card and includes a window through which either the red or green sector is visible.  The device may be mounted within a recess of the handle of an on/off valve to indicate correct and incorrect positioning of the valve.  The valve is in the correct position when the green sector appears on the window and is incorrectly positioned when the red sector appears in the window.  A locking tab projects from the housing and is received within one of two detents of the valve handle to align the window with either the red or green sector, respectively, when the handle is moved to the open position and vice versa.

Abstract: A child carrier includes a frame, wheels disposed at the lower portion of the frame, a hand-pushed bar joined to the frame, a seat attachable to the frame by a fore swing arm and a rear swing arm. The fore swing arm and the rear swing arm are hinged respectively to the front and rear of the frame and are capable of swinging the seat. The child carrier further includes a switching device that permits a caregiver to adjust the distance between the lower ends of the fore and rear swing arms so that the seat can swing in a horizontal gliding motion or a pendulum type rocking motion. The carrier can also be used as a common hand-pushed carriage when the seat is fixed. The child carrier further includes an anti-swing latch capable of coupling the frame to the fore swing arm to prevent the seat from moving relative to the frame.      The seat is adjustable to provide a forward or rearward facing stroller or carriage seat and is removable from the frame to provide a bassinet. The seat includes a seat back, a seat bottom, a foot rest, and an extendible front bar that may be positioned in different positions relative to each other so that the child carrier may be configured in a carriage position or stroller position. The frame is collapsible and movable between an unfolded use position and a folded storage position.

Title: A control system for a vertical vane covering for architectural openings
Inventor: THOMSON EUGENE W
IPC: E06B9/36
Filed: 1997-09-30
Abstract: A control system for a vertical vane covering for an architectural opening includes a new and improved symmetric headrail having uniquely designed carriers for suspending individual vanes wherein the carriers are designed to minimize skewing relative to a tilt rod as they are moved along the headrail. A pantograph system is utilized to interconnect the carriers, and is connected to the carriers in alignment with the tilt rod so as to minimize skewing. The carriers have pockets formed therein through which the traverse cord extends so that the traverse cord, which moves the carriers along the tilt rod, is secured to a lead carrier closely adjacent to the tilt rod to, again, minimize skewing.      Light blocking rails are also attachable to the headrail to substantially bridge the gap between the headrail and the top of the suspended vanes to prevent light from passing therebetween. The tilt rod is keyed to gears in the carriers to facilitate assembly of the control system with all vanes properly aligned.

Title: Input signal reading circuit having a small delay and a high fidelity
Inventor: SUTO SHINICHI
IPC: H03K5/1252
Filed: 1997-11-10
Abstract: An input signal reading circuit comprises an up-down counter receiving an input signal and a sampling clock to count up the sampling clock when the input signal is at a high level and to count down the sampling clock when the input signal is at a low level. The up-down counter outputs an underflow signal when a count value of the up-down counter becomes zero. A comparator compares the count value of the up-down counter with a reference value held in a register, to generate a coincidence signal when the count value of the up-down counter becomes coincident with the reference value. A RS flipflop is set by the coincidence signal to bring the read-out signal into a high level, and is reset by the underflow signal to bring the read-out signal into a low level.
