Title: Device and method for detecting microorganisms
Inventor: READ KAREN A
IPC: C12M1/24
Filed: 1996-06-04
Abstract: A method and a sealable, sterilizable vessel (36) for detecting the presence of microorganisms in a specimen, the vessel contain-ing a liquid culture medium and a sensor (37) with an indicator medium therein. A gas permeable membrane (31) with a gas im-permeable removable seal (32) thereon are provided in a wall of the vessel. If the microorganism to be detected is an anaerobic organism, then the gas impermeable seal (32) is left in place. If the microorganism to be detected is an aerobic organism, then the gas impermeable seal (32) is removed so as to allow the passage of oxygen into the vessel. In a preferred embodiment, the gas perme-able membrane (31) allows the passage of oxygen into the vessel while at least partly restricting the passage of carbon dioxide to outside of the vessel. Changes in the indicator medium resulting from a change in gas production (CO2, NH2, H2S, etc.), volatile acid production or pH concentration in the medium, are detected from outside the vessel.

Title: Information transmitting method, encoder/decoder of information transmitting system using the method, and encoding multiplexer/decoding inverse multiplexer
Inventor: KIKUCHI YOSHIHIRO
IPC: H04N19/44
Filed: 1997-09-02
Abstract: An information transmitting method by which a bit string can be decoded normally even when an error occurs in such important information as header information by imparting an error resistance to the bit string itself. The bit string reconstituting circuit (107) of an encoder adds a synchronizing signal to the first part of an encoded data string in units of a certain fixed bit string encoded by an encoding circuit (103) and, thereafter, inserts instruction information into the bit string by using an instruction information inserting circuit (106). This instruction information represents the addition of information for restoring important header information, and the instruction information is inserted into the bit string. Therefore the information for restoration can be added to the encoded data string. Further, even when the header information cannot be used for decoding due to an error mixed in the header information, the decoding can be continued normally by using the new information for restoration represented by the instruction information in place of the header information.

Title: Payphone metering in a wireless telephone system
Inventor: ROBBINS BARRY R
IPC: H04W4/24
Filed: 1997-06-11
Abstract: The wireless system includes one or more payphones (12) from which users may initiate payphone calls.      A mobile switching center (16) connects telephone calls initiated from wireless payphones to external telephone systems (18) such as the publlic switch telephone network (PSTN). To meter charges incurred during the telephone call within an external system, the external system transmits periodic metering pulses (52, 54) to the mobile switching center. Each pulse is representative of a predetermined amount of money associated with the telephone call. The rate at which the periodic pulses are transmitted to the mobile switching center depends upon the current billing rate and may be affected by, for example, the time of day. Rather than the forwarding all of the metering pulses to the wireless payphone, therefore consuming a portion of the bandwidth available for wireless telephone calls, the mobile switching center (16) calculates a steady state billing rate from the metering pulses, then transmits only the steady state billing rate to the wireless payphone (12).
