Patent GB-2236645-A (GB)
Title: Method for expediting the rendering of figures in a move-draw language
Inventor: DONATO NOLA
IPC: G06T17/00
Filed: 1990-05-08
Abstract: A method of implementing a move-draw format to control the operation of a graphics accelerator of a computer system which includes the steps of providing a figure type designation (eg TR1) in a process description (Fig 4) in said format, for rendering an element, defining the total element being drawn (Fig 3), referring to the type designation (TR1) to determine whether the graphics accelerator is able to implement an algorithm for such type, and selecting the individual coordinates from the format (eg steps 4, 8, 16, 20) to implement the process while ignoring the move-draw elements (eg LINE, step 12) if the graphics accelerator is capable of implementing the algorithm. Slow step by step rendition of a figure is thereby replaced by the graphics acceleration algorithm. <IMAGE>

Title: Selective printer with ink-ribbon feed and paper bail opening motions driven from a common motor
Inventor: KODAMA HIDETOSHI
IPC: B41J13/20
Filed: 1991-07-24
Abstract: A paper bail operating device for a printer including a platen 15, a paper bail and a hinged paper bail support device movable to bring the bail into and out of engagement with the platen, is driven by reverse operation of a ribbon drive motor 1. The motor 1 has a pinion 1a in mesh with a ribbon drive gear 3 connected to a ribbon drive shaft 5 through a one-way clutch. The gear 3 is in mesh with an intermediate gear 8 carrying a paper bail drive gear 9, both rotatably mounted on a support plate 6 pivoted about the axis of the gear 3. The paper bail support device includes an extension arm 14e engaged with a second arm 13 of a paper bail drive means A including a first pivoted arm 12 carrying a gear segment 12a. In operation, the motor 1 when driven to rotate the ribbon drive shaft causes the support plate 6 to pivot the gear 9 out of contact with the gear segment 12a. When the motor is driven in the opposite direction, the support plate 6 pivots to bring the rotating gear 9 into contact with the gear segment 12a, thus rotating the arm 12 about its axis and making the arm 13 push the extension 14e to bring the paper bail out of contact with the platen 15. <IMAGE>

Title: Power saving supply for cellular telephone
Inventor: MENADUE ANDREW
IPC: H04B7/26
Filed: 1991-08-02
Abstract: A portable cellular radio telephone (1) comprises a transceiver including a voltage controlled variable gain amplifier (11) operable at one of a plurality of predetermined output power levels selected automatically under the control of a microprocessor (4) in response to a signal from a base station indicative of a requirement for a change in level of the output power. A battery save mode can be manually selected which causes the output power at the maximum power level to be reduced to a value below the nominal value of the maximum power level imposed by the system specification. Power consumption is thus reduced when the transceiver is transmitting at maximum power, and battery life is therefore extended. The battery save mode may be selected from a menu which can be viewed on a display (5). The respective menu function can be accessed and enabled/disabled by using the keys (6a, 6b) on the telephone keypad (6). The selection and de-selection of the battery save mode may be accompanied by a legend such as "BATTERY SAVE ON" and "BATTERY SAVE OFF" on the visual display. <IMAGE>
