Title: Methods of learning the characteristics of a telephone
Inventor: STELMAN BRUCE W
IPC: H04M3/26
Filed: 1997-03-27
Abstract: The present invention overcomes interface problems between proprietary hands et ports on telephone base units and voice/data accessory products by allowing a user  to automatically calibrate the telephone accessory product for an optimal interface match with the intended telephone base unit. This is accomplished through the use of a "Smart Interface Technology" (SIT) integrated chip set consisting of a full custom analog and semi-custom digital integrated circuit. The SIT incorporates methods for "learning" the characteristics of 4-wire port modular interfaces found in all telephone station sets by determining the appropriate 4-wire terminal configurations, the transmit and  receive channels of the intended telephone base unit, and adjusting the channel sensitivities until an optimal and clear signal is provided for the user.

Title: Dental crowns and/or dental bridges
Inventor: FILSER FRANK
IPC: A61C5/77
Filed: 1999-03-16
Abstract: The invention relates to a method and a blank for producing artificial dental crowns (28) and/or dental bridges (38) which can fit on at least one prepared stump (10). The three-dimensional outer and inner surfaces (20, 22) of a positive model (46) of the base frame (14) for the dental crowns (28) and/or for the dental bridges (38) are scanned and digitized. The determined data is linearly expanded around a factor (f), said factor exactly compensating the sinter shrinkage, in all spatial directions. The data is also transmitted to the control electronics of at least one processing machine for processing the blank (48) made of porous ceramic, and the appropriate tool paths are derived therefrom. Material which is temporally decoupled from the digitization is removed from the blank (48) by means of control commands for the tools. Said material is removed until an enlarged finished form of the positive model (46, 47) is produced. This enlarged base frame is tightly sintered to the base frame (14) with direct final measures. Finally, the base frame (14) is individualized by enameling with a coating material (24) made of porcelain or plastic. An information code which is provided for the enlargement factor (f) and which can be detected by a mechanical or human sense organ is placed on the ceramic blank, the packaging thereof, a label or on an instruction

Title: Extendable bay window for mobile living quarters
Inventor: VANCE DENNIS R
IPC: E06B5/00
Filed: 2000-11-02
Abstract: The present invention involves a foldable bay window for mobile living quarters, such as recreational vehicles, is movable between an extended position, in which the bay window projects from a wall of the unit to a folded position, in which the components of the bay window assembly are substantially flat against the outer wall of the unit. The bay window assembly includes a pair of side panes which are slidably and pivotally mounted on horizontally extending tracks on the wall of the unit, and a center pane connecting the side panes. A bottom panel is pivotally connected to the wall or center pane and is constrained for movement along vertical tracks, to thereby force the panes into the folded position as the bottom panel is moved from a substantially horizontal position to a substantially vertical position. As the panes are folded against the wall of the vehicle, a hinged roof panel drops into a substantially vertical position. The bay window assembly may also be located on the ceiling of the mobile living quarters, with a roof pane being capable of pivoting to an extended position to support the side panes.

A metal hose is connected and coupled with the pedal member, and is inserted and mounted the steel wire inside thereof. A packing shaft member is operated according to the up and down movement of the steel wire connected and coupled with an end of the steed wire interpolated to the metal hose and the metal hose member. A  packing shaft housing guides the up and down movement by interpolating of the packing sha8 member. A valve body assembly is accepted and fixed the packing shaft housing, is equipped a water-entrance for supplying water from the outside on a lateral side, and is mounted a water-outlet for discharging the supplied water from the water-entrance. And a metal hose-coupling member fixes and couples the metal hose to the main body.

Title: Human-powered energy generation and transmission system
Inventor: DAVIS DONALD L
IPC: B62M6/85
Filed: 1999-04-16
Abstract: Efficient human-powered or human-power assisted energy generation and transmission system adapted for use with vehicles. The present invention can be utilized to achieve overall energy transmission efficiency superior to mechanical drives that utilize chains and sprockets or other mechanical drive mechanisms. The present invention can completely eliminate the need for multiple sprokets and the associated shifting mechanisms presently used in most bicycles. By utilizing high efficiency, light weight, direct-drive generators and motors, and an imput controller, coupled with an efficient energy storage device, the present invention can reduce the overall weight and complexities of mechanical power transmissions, while, at the same time, offer higher overall efficiencies. In addition, the energy output to the output drive device can be controlled, through profiling and with an output controller, to maintain constant output, independent of instantaneous input. Thus, in a human-powered vehicle, constant thrust can be maintained significantly increasing the vehicle efficiency, compared to the cyclical thrust or torque generated using a mechanical system.
