Patent EP-0551973-A2 (EP)
Inventor: RHINES DON S
IPC: H03M13/31
Filed: 1993-01-07
Abstract: The detection and correction of errors in digital data transmitted by or stored in a media channel is provided by processing the data through a triple orthogonally interleaved error correction system. On the transmit/store side of the system, the data is encoded three times prior to placement in the media channel with two different interleaving steps performed between the encoding steps. The first interleave is an orthogonal row shuffling interleave that provides enhanced protection against burst errors. On the receive/play back side, the data is decoded and deinterleaved, with included errors detected and corrected to enable recovery of the original data. To enhance the error correction, a circuit is used for generating a symbol accurate error flag identifying symbols containing errors thereby allowing the error correcting decoders to focus on and correct the data.

IPC: G01B9/02

Abstract: 2.1 Known measurement methods and measuring arrangements have the disadvantage that the measurement of the phase change in the interference signals which is necessary for determining the measured distance is performed with a resolution of at most approximately 1/10 of the total wavelength. However, this resolution comes nowhere near the resolution which can be achieved using other methods. Moreover, because of the ignorance of the wavelength no relative measurements can be carried out following an absolute measurement. 2.2 This disadvantage is overcome in the measurement method according to the invention owing to the fact that at the ends of each measurement cycle the air wavelength of the laser beam is controlled to a specific wavelength value by means of an additionally provided control interferometer having a control section which is shorter than the measurement section and thereafter the air wavelength is continuously tuned within a specific wavelength interval and controlled to the final value by means of the control interferometer. The phase change in the interference signal is continuously detected during the wavelength modulation. A simple mathematical relationship can be used to determine the measurement section from the measured wavelengths and the phase shift. Relating the measurement uncertainty of this method to that of the conventional interferometers can be achieved by using a further laser having at least one further discrete wavelength by generating a beat wavelength, which must be greater than the measurement uncertainty owing to the continuous tuning of the wavelength. It is possible, furthermore, to use this method to carry out relative measurements following an absolute measurement. 2.3. The measurement method and the laser interferometer arrangement are suitable, in particular, for absolute distance measurements. <IMAGE>

Abstract: Voice, facsimile, and electronic mail messaging is integrated in a system that converts e-mail messages into voice-and-fax messages. An e-mail message (400) is parsed into voiceable, prose, segments (403) and non-voiceable, non-prose, segments (404). Prose segments are converted into voice message segments (503) via text-to-speech facilities. Each non-prose segment is converted into a fax segment (504). Voice pointers (505) to fax segments are inserted into the voice message, in places corresponding to the non-prose segments in the e-mail message. The voice file (500) and fax file (510) are then stored for subsequent delivery of the message as an integrated voice-and-fax message. Conversion of integrated voice-and-fax messages into e-mail messages is likewise envisioned.

Abstract: A seat belt retractor (10) includes a seat belt webbing storage spool (14) that is rotatable in winding (retraction) and unwinding (withdrawal) directions. First and second springs (50 and 52) bias the spool (14) in the retraction direction and are stressed upon rotation of the spool in the belt withdrawal direction. A connector (54) interconnects the first and second springs (50 and 52). The connector has first and second portions (66 and 64) which are movable relative to each other. The first portion (66) is connected to the first spring (50), and the second portion (64) is connected to the second spring (52). An actuatable mechanism (56), when actuated, blocks rotation of the second portion (64) of the connector (54) in the belt retraction direction to block the spring force of the first spring (50) from acting through the second spring (52) and on the spool (14). The actuatable mechanism (56), when deactivated, releases the second portion (64) of the connector (54) to permit the first spring (50) to apply force through the connector (54) and the second spring (52) to the spool (14). The connector (54) includes a mechanism which acts between the first and second portions (66 and 64) for damping the force applied to the second spring (52) by the first spring (50) upon deactivation of the actuatable mechanism (56).

Abstract: A cordless telephone arranged for operation in a frequency hopping system includes multiple portable units configured for operation with a base unit and with each other by having the base unit pseudo randomly select from a plurality of communication channels available in the frequency hopping system a different starting channel for each one of the portable units. Each portable unit then provides initial communications with the base unit over the selected starting channel of the portable unit. For maintaining communications during a frequency hopping cycle between a portable unit and the base unit, the portable unit and base unit both generate a set of communication channels from the starting channel assigned to the portable unit for subsequent use in communicating over the radio frequency link. Each of the portable units is configured for operation with the base unit and with each other during a registration procedure. Information indicative of the starting channel for each portable unit and also a security code is transmitted to each of the portable units from the base unit during this registration procedure and on a predetermined communication channel at a radiated energy level well below the level normally used for normal communications.

Abstract: The pliers have two arms connected by a pivot pin (4) and adjustable in a stepwise manner to open or close the gap (M) between the jaws (5,6). The first arm (2) passes through a dividing slot in the other (3). The pin has limited axial movement in holes (14) in two side walls of the second arm and has diametrically opposed flats (19,20) which allow it to fit between the sides (12) of a slot (11) in the other arm. The slot has rack teeth on each side which engage with teeth (21) on the pin flats and lock the pin rotationally and positionally. To adjust the jaws, the pivot pin is pushed from the head end (15) against the pressure of a leaf spring (23). This moves the pin sideways out of engagement with the slot teeth so that it, together with the arm can be adjusted along the slot.
