Abstract: Safety equipment for passenger conveying plants, in particular for escalators and moving walkways with at least one comb plate which actuates a safety switch by way of trigger means in the case of a force action exceeding a settable amount in horizontal or in vertical direction. The comb plate is movable horizontally and vertically against the static force of a force F or against its components Fh and Fv. The static triggering force F is set by means of a biasable spring (5) and divided into the static triggering force components Fh and Fv by an adjustable angular position of the line of action of the spring (5). The ratio Fh:Fv is selectable by appropriate angular position of the line of action of the spring (5). The setting of the angular position is possible by simple manual resetting within a certain angular range without constructional action on the safety equipment.      Detent notches (12) and detent pins (13) assure a constant maintenance of the set angle.

Abstract: In a speech decoder which experiences frame erasure, the pitch delay associated with the first of consecutive erased frames is incremented. The incremented value is used as the pitch delay for the second of consecutive erased frames. Pitch delay associated with the first of consecutive erased frames may correspond to the last correctly received pitch delay information from a speech encoder (associated with a non-erased frame), or it may itself be the result of an increment added to a still previous value of pitch delay (associated with a still previous erased frame).

Granted: 2008-01-29
Abstract: A method of electrically connecting an integrated circuit (IC) to at least one electrical conductor on a flexible substrate. A flexible dielectric substrate has an IC attachment area and at least one resonant circuit formed thereon. The resonant circuit is formed with a first conductive pattern disposed on a first principal surface of the flexible substrate and a second conductive pattern disposed on a second, opposite principle surface of the flexible substrate. The first conductive pattern is electrically connected to the second conductive pattern such that the first and second conductive patterns form an inductor and a capacitor, with the inductor also functioning as an antenna. The IC attachment area of the flexible substrate is cleaned and the flexible substrate is secured in a fixed position in a plenum to prevent substantial movement thereof. The IC is secured to the IC attachment area of the flexible substrate to minimize movement of the IC relative to the flexible substrate. Wire bonding of the IC to at least one electrical conductor of the resonant circuit is performed to electrically connect the IC to the at least one electrical conductor. A protective covering is applied over the IC and the wire bond to protect the wire bond from being damaged by external forces.

Title: On-demand fast cycle mold
Inventor: PHILLIPS ROBERT
IPC: B29C45/27
Filed: 1997-09-18
Granted: 2006-07-11
Abstract: An on-demand fast cycle mold for producing injection molded products such as polypropylene blister package bases. The on-demand fast cycle mold has a heated and cooled hot runner system which provides a short response time and optimal temperature control. On-demand injection molding is made possible by a pulse modulated closed loop mold cooling system, the cooling design of brazed gate inserts, and an effective layout of the cooling channels. The programming of the software for a computer control system has also been designed to achieve on-demand injection molding. The design of the closed loop mold cooling system incorporates an advanced cooling circuit layout, and provides for easy maintenance and better quality control of the coolant which significantly reduces corrosion and scale buildup.      Mold cooling is controlled by sensors installed inside the mold which are used in feedback control loops.      The brazed gate inserts provide precise mold temperature control and improved cosmetic appearance of the molded packages. The use of a needle-valve injection nozzle results in reduced cycle time and improved moldability.

Granted: 2006-08-29
Abstract: A gastrointestinal delivery system is provided. The system comprises a drug in combination with a core material, the core being surrounded by a water-insoluble or relatively water-insoluble coating materi al in which particulate water-insoluble material is embedded. When the delivery device enters the gastrointestinal tract, the particulate matter takes up liquid, thus forming channels interconnecting the drug-containing core with the outside of the delivery device. These channels allow the release of drug from the core into the gastrointestinal tract. By controlling parameters in the device, such as the core material, carrier material in the coating, and particulate matter, the location of release of the drug can be carefully controlled. Thus, the invention is also directed to a method of using the device for the treatment of disease by the release of drugs in the gastrointestinal tract in a location- and time-dependent manner.

Title: Method for transmitting multiresolution audio signals in a radio frequency communication system
Inventor: MATTHEWS DAVID G
IPC: G10L19/02
Filed: 1997-10-03
Granted: 2006-03-28
Abstract: The present invention relates to a method for transmitting multiresolution audio signals via wireless devices in a radio frequency system wherein audio signals are decomposed into levels of resolution (38).  The audio signals is decomposed into levels including a base signal at a base transmission rate and one or more signal details. The base signal represents the coarsest resolution or quality of the signal. Each signal detail, when added to the base signal, improves the resolution of the signal by increasing the detail and the transmission rate. An audio receiving unit (50) transmits a request for audio transmission to the audio transmitting unit (30). In response to the initial request, the base signal is transmitted to the audioreceiving unit. If the base signal is insufficient, the sound quality can be increased incrementally by sending further request to transmit additional signal detail. The additional signal detail is then recombined with the base signal at the audio transmitting unit to provide a higher level of sound quality to the signal. The higher quality audio signal is then transmitted to the audio receiving unit.
