Title: Including missing parties in active trunked group calls
Inventor: BAR-ON DAVID
IPC: H04W84/08
Filed: 1992-04-04
Abstract: A trunking radio system is provided comprising at least one radio base site 11 to 14 and a plurality of radio units 15 to 17 grouped into at least one talk group. Means are provided for transmitting a message, eg a go to channel (GTC) command, to the talk group of radio units 15, 16 indicating that a call is to commence for that talk group. The radio units switch to an allocated channel on receipt of the message. The system re-transmits the message when and substantially only when a new radio unit 17 enters the system by requesting registration and is a member of the talk group. Thus the new radio unit can enter the call but the system is not over burdened with re-transmission messages. Re-transmission can be suspended for a set period. A radio unit may transmit a different registration request when communication is required after being lost, and these requests can be counted to indicate if a unit has difficulty registering. <IMAGE>

Patent GB-2287760-A (GB)
Title: Gas-tight seal
Inventor: HOSKIN WILLIAM JOHN
IPC: A61B17/34
Filed: 1994-10-13
Abstract: A gas-tight seal module 6 is incorporated in a trocar system to form a gas-tight seal about an instrument 12 inserted into the cannula of the trocar system. The module 6 incorporates an apertured disc 30. The aperture in the disc can be stretched to accommodate a seal about an instrument 12 inserted into the cannula. The disc is carried by a flaccid membrane 20 which extends across the module 6. A pair of rigid washers 32 and 34 clamped on opposite sides of the disc 6 are constrained for movement between two parallel spaced surfaces. The disc is thus freely moveable in its own plane to accommodate off-axis movement of the instrument so avoiding the breakage of the seal with the instrument which would otherwise occur if the disc did not have the same freedom of movement. The disc 30 also acts to clean the surface of the instrument when withdrawn so as to avoid contamination of a flap valve 10 upstream of the disc 30. <IMAGE>

Title: Multiple font display
Inventor: KEEN DONALD MARION
IPC: G09G3/36
Filed: 1994-11-30
Abstract: More than one font can be displayed on a limited dot matrix display device. In addition to displaying characters in a standard font based on using all pixels in a five by seven pixel matrix, a custom font set based on a reduced size pixel matrix is used for character display. A maximum of four columns and six rows of pixels, i.e., a four by six matrix, are used for the custom font out of the five columns and seven rows of pixels which are available. The pixels which are not used to create a character may be used to add a background characteristic. Thus a reverse video font or underlining font may be created. A box can be placed around a word by using the underline font in conjunction with placing a vertical line immediately before the first character and immediately after the last character of a word to be placed in a box. <IMAGE>
