The invention relates to a mobile communications device comprising a housing, a transceiver in the housing, a keypad connected to the housing, and a display connected to the housing, wherein the housing comprises a first section movably connected to a second section of the housing by a multi-axis hinge, wherein a first axis of rotation of the hinge is provided at the first section of the housing and a second offset axis of rotation of the hinge is provided at the second section of the housing, a...

A device for synchronizing multiplex lines in a time-division exchange comprising an input register, local and distant counters, a memory with a capacity of two frames, a frame alignment word detector, a write time select circuit, a decision circuit providing a frame skip or frame repetition facility for memory read operations, a circuit for addressing the memory in write and read modes and an odd parity injection circuit.

A control device for forging machines having a plurality of hydraulically actuated forging tools for reducing the cross section of a workpiece. In order to increase the forging accuracy the actual characteristic of each forging tool at the end of the forging stroke is compared with a predetermined characteristic and, when the characteristics differ, a servo-control mechanism supplies pressure fluid to or withdraws it from the line interconnecting a pump cylinder of the drive mechanism with the r...

A method and apparatus for synchronising the speed of filming of a cine-camera with the rate of a projector in which a marking is made on each frame of a movie film during shooting, this marking having characteristics corresponding with a certain image frequency in shooting, which markings can be read at the time of projection in order to control or provide control for the speed of projection.

A receiving apparatus for receiving signals in a digital telecommunication system and a synchronizing method for synchronizing the receiving apparatus. The receiving apparatus includes a receiver for receiving a reference symbol having at least two repetition patterns. One of the, repetition patterns is phase-shifted in relation to the other. The receiving apparatus is synchronized in the digital telecommunication system using the received reference symbol. The synchronization includes a cross c...

A self-synchronising data bus analyser comprising a generator LFSR, a receiver LFSR and a comparator wherein the generator LFSR generates a first data set which is transmitted through a data bus to the comparator; and wherein the comparator compares the first data set with a second data set generated by the receiver LFSR and adjusts the receiver LFSR until the second data set is substantially the same as the first data set.

A circuit 100 for determining the polarity of an input sequence of pulses 200 or 300 applied to input 102 by digitally determining the polarity of a predetermined number of pulses of the input sequence of pulses using the digital polarity determinator 130 and, dependent on the output of the digital polarity determinator 130, routing the input sequence of pulses by the polarity switch 120 to the output 135 when the polarity of the input sequence of pulses is a predetermined polarity, and routing ...

A method and apparatus is provided for locking a local oscillator to a reference oscillator. The reference oscillator is arranged to transmit a signal containing two reference pilot tones in a signal sideband. The apparatus samples the received signal and makes a frequency shifted copy where the shift is equal to the expected separation between the reference tones. The non-shifted and shifted signals are then combined in the frequency domain to constructively reinforce one of the reference pilot...

Methods, systems and machine readable media for synchronising three or more electronic devices.In one exemplary method of synchronising three or more electronic devices, said method comprises: a) selecting at least one category of record for synchronisation; b) storing an original value and a changed value of each changed record from a selected record category; c) establishing an electronic connection between at least two devices; d) comparing the records of the selected record categories; e) de...
