Abstract: A synchronizing method in a mobile radio system which operates with Time Division Multiple Access (TDMA) but which lacks global time reference for all base stations and mobiles in the system.      The inventive method is intended for ciphered transmission of data and speech in accordance with a given ciphering key (E2). When handing-over a call, the ciphering synchronism is lost. In accordance with the method, subsequent to hand-off (the time t2), the take-over base station (BS2) signals non-ciphered information (S1) to the mobile (MS) disclosing the number of frames (R1-R13) which shall pass until ciphering can again be commenced, calculated from a given frame (R1). Call information is transmitted in the following frame (R2), this information now being ciphered with the aid of a ciphering key (E1) different to the original key. This other ciphering key consists of a periodic bit sequence having a period which is equal to one frame interval.

Title: Motion compensation encoding of a picture input signal into a picture output signal of a predetermined bit rate
Inventor: OHKI JUNICHI
IPC: H04N19/85
Filed: 1992-10-23
Granted: 1998-09-29
Abstract: Derived from a picture input signal and a motion vector signal in a block matching type motion compensation encoding device, a prediction error signal is quantized by a controllable quantizer into a quantized signal for encoding together with the motion vector signal.  Supplied with frame pulses, a controller produces a control signal with a predetermined value for making the quantizer quantize a zero signal instead of the error signal and with a different value for operating the quantizer merely as a forward quantizer.  An amount of encoded information is reduced when the predetermined value appears once in two or three frame periods.  For smoother movement of a movable part in reproduced pictures, the zero signal is not substituted in each duration in which motion vectors are either greater in magnitude, not identical with a representative vector, or less correlated with corresponding motion vectors in a previous picture for which the zero signal is not substituted.  Each duration may be an interval of time during which the error signal has a greater absolute value.  The controllable quantizer may be a combination of the forward quantizer and a selector controlled by the control signal to select the zero signal and either the error signal or an output signal of the forward quantizer.

Granted: 2000-09-26
Abstract: A first bill feeding plate 33 and a second bill feeding plate 34 cooperatively constitute a bill feeding passage 31 of a bill discrimination apparatus 1. The first bill feeding plate 33 is formed at a. bottom of a casing 67, which is swingably supported on the second bill feeding plate 34 through a hinge shaft 36. An opening lever 82, having an engaging hook 83 and an operating projection 84, is swingably supported at a distal end of the casing 67. The first bill feeding plate 33 is fixed to the second feeding plate 34 when the engaging hook 83 is engaged with an engaging piece 94.      Pulling up the operating projection 84 causes the opening lever 82 to start a swing motion about a bearing piece 87. This causes the engaging hook 83 to separate from the engaging piece 94, and the casing 67 rotates in a counterclockwise direction. Thus, the first bill feeding plate 33 separates from the second bill feeding plate 34 to widely open the bill feeding passage.

Granted: 1995-04-25
Abstract: An essentially jam-free bulk loader for a semi-automatic paintball gun includes a storage housing positionable above the gun infeed opening and adapted to hold a quantity of paintballs to be gravity fed to and fired by the gun.  Extending downwardly from a bottom outlet opening in the housing is a feed tube having a bottom end portion connectable to outer end of the gun infeed elbow.          During normal operation of the loader, a series of paintballs fall into the tube and infeed elbow and are vertically stacked therein for sequential downward delivery to the gun through the inner end of the infeed elbow.  If a paintball jam occurs within the storage housing above its outlet opening during firing of the gun, a void is created in a top end portion of the feed tube above the downwardly moving paintball stack.  An optical sensor detects the void and responsively actuates a motor driven agitator member within the storage housing adjacent its bottom outlet opening.  The driven agitator member forcibly engages and shifts the jamming paintballs to permit additional paintballs to fall through the housing outlet opening into the feed tube and return the paintball delivery stack to its full operating height within the tube and infeed elbow.  When this occurs, the sensor detects the filling of the tube void and responsively terminates the operation of the agitator member until it is needed again.

Title: Process for reducing data in the transmission and/or storage of digital signals from several dependent channels
Inventor: HERRE JURGEN
IPC: G10L25/00
Filed: 1992-10-13
Granted: 2003-12-02
Abstract: A method for reducing data during the transmission and/or storage of the digital signals of several dependent channels is described.   The dependence of the signals in the channels, e.g. in a left and a right stereo channel, can be used for an additional data reduction. Known methods such as middle/side encoding or the intensity stereo process lead to perceptible interference in the case of an unfavourable signal composition.   The method according to the invention avoids such interference, in that a common encoding of the channels only takes place if there is an adequate spectral similarity of the signals in the two channels.   With the aid of the method according to the invention an additional data reduction can be achieved in that in those frequency ranges where the spectral energy of a channel does not exceed a predeterminable fraction of the total spectral energy, the associated spectral values are set at zero.   As the method is independent of the specific internal form of the encoding method, it is universally usable.
