Title: Laser range finder
Inventor: SHYY YEU-HWA
IPC: G01S17/14
Filed: 1992-10-23
Abstract: In a laser rangefinder which transmits laser pulses and receives them after reflection, range being determined from the pulses' time of flight, delays lines 411, 413 ensure that internal delays are compensated for so that the difference in time between the outputs of delays 411, 413 equals exactly the time of flight of the pulses. This time is determined by further delaying 412 the delayed transmitted pulse until the further delayed transmitted pulse coincides with the delayed reclined pulse; the further delay then corresponds to the time of flight. Searching for coincidence may be facilitated by arranging for the delayed received pulse to be lengthened initially by delay 413, and then coarse coincidence is established, shortening it. <IMAGE>

Patent GB-688961-A (GB)
Title: Improvements relating to laminated fabrics
IPC: D06M17/02
Filed: 1951-01-13
Abstract: 688,961. Compound fabrics. CELANESE CORPORATION OF AMERICA. Jan. 13, 1950. [Jan. 13, 1949] No. 928/50. Class 140. Launderable stiffened fabrics suitable e.g., for shirt collars and cuffs are made by bonding a layer of fabric containing non-thermoplastic yarn and having a coating of a precipitated cellulose derivative to one or more other fabric layers by pressing the fabric layers together at an elevated temperature in the presence of a plasticiser and a volatile liquid that is not a solvent at ordinary temperatures but assists the coalescence of the cellulose derivative particles at the bonding temperature. The coated fabric, which may be woven, knotted, or netted from yarns of cotton, linen, wool, silk, or regenerated cellulose, is coated all over or locally with a solution of a cellulose derivative such as the acetate in a volatile solvent such as acetone, which has been diluted with a non-solvent such as water until the point of incipient precipitation is reached. The coated fabric is then subjected to the action of non- solvent vapour, e.g. steam, which causes the cellulose derivative to precipitate in discrete particles. The coating solution or the fabric may be heated before coating. The other fabrics may be of cotton, linen, wool, or silk. The plasticiser, which may be incorporated in the volatile liquid, the coating solution, or in one of the fabrics, may be dimethoxyethyl, diamyl, dibutyl, or diethyl phthalate, butyl phthalyl butyl glycollate, dibutyl tartrate or sebacate, dimethoxyethyl adipate, tributyl, tricresyl, or triphenyl phosphate, ethyl sulphonamide, triacetin, tributyrin, triethylene glycol diacetate or dibutyrate. The volatile liquid may be aqueous methanol or ethanol, or a solution of acetone in ethanol. Instead of cellulose acetate, the propionate, butyrate, acetate-propionate, acetate-butyrate, nitrate, or ethyl or benzyl ether may be used.

Title: Multiplex addressing of ferro-electric liquid crystal displays
Inventor: HUGHES JONATHAN RENNIE
IPC: G02F1/133
Filed: 1993-01-27
Abstract: A ferro-electric crystal cell is addressed by row and column electrodes forming an x,y matrix of display elements. A strobe waveform is applied to each row in sequence whilst appropriate data waveforms are applied to all the column electrodes. At each display element the material receives an addressing waveform to switch it to one of its two switched states depending upon the polarity of the addressing waveform. The switching characteristics of ferro-electric materials depend upon the shape of the addressing waveform. Two different shapes of addressing waveforms are used to produce two different and separated switching characteristics (Fig. 3). At least one switching characteristic curve may exhibit a minimum response time at one voltage value, and the display is operated at voltages above this. The data waveforms are alternating positive and negative pulses of period 2ts. The strobe waveform has a zero for one time period ts followed by a unipolar voltage pulse of duration greater than ts, e.g. 1.5ts or more. This results in an overlapping of addressing in adjacent rows, i.e. the end of a strobe pulse on one row overlaps with the beginning of a strobe pulse on the next row. The display elements may be switched into one of their two states by one of two strobe pulses of opposite polarity. Alternatively a blanking pulse may switch all elements to one state and a strobe used to switch selected elements to the other state. <IMAGE>

Title: Telephone with speed dialing
Inventor: MOTT ALEXANDER PAINE
IPC: H04M1/2748
Filed: 1994-05-17
Abstract: A telephone, e.g. a mobile telephone, has a standard set of telephone dialing digit keys (9a) for the numeric digits 0, 1 ... 9 and the characters "*" and "#". The telephone also includes an abbreviated dialing memory (11) for speed dialing. Predetermined ones of the dialing digit keys (9a) have a dual function for one-touch speed dialing. If any of these predetermined keys is pressed for a period of time less than a threshold value, the normal digit associated with that key is selected, e.g. for regular dialing purposes. On the other hand, if one of the predetermined keys is pressed for a period of time equal to or exceeding the threshold value then a telephone number is retrieved from a predetermined memory location and a call to the retrieved telephone number is automatically initiated without pressing any further keys. For example, when the "*" or "#" keys are pressed for more than 2 seconds a call is initiated to a pre-programmed number stored at a respective predetermined location in the abbreviated dialing memory (11). If the "9" or "0" is pressed for more than 2 seconds a call is automatically initiated to a pre-stored emergency number or operator number respectively. <IMAGE>

Title: Distributed method of call arbitration in an RF trunking multisite coordinator architecture
Inventor: KENT JAMES S
IPC: H04W84/08
Filed: 1995-01-30
Abstract: Transceiver sites 102A...102N, serving respective areas, are connected via respective interface modules 203A...203N to a multisite coordinator/switch, and in order to avoid performance bottlenecking and a "single point of failure" configuration that would arise in a conventional centralized arbitration arrangement, contention between calls in a common talk group is arbitrated at each interface 203 autonomously based on a common arbitration scheme implemented at all interfaces. The scheme can be described as "first call wins, tie goes to highest numbered site". An interface sets a transmit busy flag when a call is originated by a mobile served by the associated site 102. If a call is then received at the interface from another site, that one of these calls which is from the site of higher pre-assigned ID number wins the contention. An interface alternatively sets a receive busy flag when it receives a call from another site 102 (in the absence of a call originated via the associated site). If a call is then received from a mobile served by the site 102 associated with the interface, then the existing call wins (Fig. 7). In either case, the call which wins the contention arbitration is processed as an ordinary call, and the call which loses is processed as an operator console-only type call. In addition, emergency calls are given priority over non-emergency calls. <IMAGE>
