Title: Terminal adapter pooling system
Inventor: MANO HIROSHI
IPC: H04Q11/04
Filed: 1991-06-19
Granted: 1996-06-04
Abstract: In a key telephone system in which a plurality of data terminals 371 ... 37n such as personal computers are connected to a key service unit 1 connected to a plurality of ISDNs 231 ... 23m, a terminal adapter (TA) 41 is pooled so as to be usable in common for the plural data  terminals  371  ...  37n.  In  response  to a  setup signal from an ISDN (e.g.  231), the key service unit 1 selects a single data terminal designated by a subaddress included  in  the setup  signal  from  among  the  data terminals 371 ... 37n, and closes a communication channel between the selected data terminal (e.g. 371) and the TA 41,  so  that  a  status  equivalent  to  that  where  the selected data terminal 371 and the TA 41 are directly connected to each other can be established.  Thereafter, the key service unit 1 transmits a setup signal to the TA 41, and the TA 41 transmits a call to the selected data terminal  371.    When  the  selected  data  terminal  371 responds to the call from this TA 41,  the key service unit 1 closes a communication channel between the TA 41 and the ISDN 251, so that a communication link between the selected data terminal 371 and the ISDN 231 can be established via the TA 41.  During the process until this communication link can be established, since the selected data  terminal  371  and  the  TA  41  are  in  the  status equivalent to direct coupling, the key service unit 1 is not concerned in the communications between the selected data  terminal  371  and  thus  TA 41,  thus  reducing  the operational load applied to the key service unit 1.

Title: Portable transceiver and esn transfer system therefor
Inventor: YOSHIDA IKIO
IPC: H04M1/727
Filed: 1991-07-25
Granted: 1996-05-14
Abstract: A portable transceiver and an ESN transfer system for a car telephone system.  The ESN and the MSN, which are manufacturer-controlled numbers, are stored in an EEPROM mounted on the panel of the portable transceiver.  When the panel on which the EEPROM is mounted is to be replaced, only the ESN is transferred to the EEPROM of the new panel.          Upon completion of the ESN transfer, the ESN in the EEPROM of the replaced panel is rewritten to data, which would make its specific part, such as the manufacturer's ID number, to be judged "incorrect".  No ESN whose specific part is "incorrect" can be transferred.  The ESN transfer unit, connected to a connector provided in the casing of the portable transceiver, performs said ESN transfer.

Title: Label printing and data collection program generator
Inventor: LAMPRECHT DALE E JR
IPC: G06F3/12
Filed: 1993-04-08
Granted: 2001-10-09
Abstract: A program generator allows a user to create a software program capable of being executed by a remote labeler to control the printing of one or more labels and to control data collection operations thereof. The program generator stores a user entered sequence of commands selected from a set of commands that control label printing and data collection operations. The stored sequence of commands is validated in accordance with the program generator such that each command entered by the user is compared to a set of allowable commands to determine whether the command is valid or not.      During the validation of each of the commands, the program generator determines whether the parameters of the command define allowable data manipulation operations to be performed by the labeler. If not, the program generator provides an error message that identifies the particular command and the error associated with the command. The program generator allows various application files to be selectively linked together to form an application program.      Further, when downloading an application file to a labeler, the program generator automatically determines whether the application program requires a look-up file. If so, the program generator creates the necessary look-up file.

Granted: 1995-12-19
Abstract: A clamping assembly (10) which provides a un-iform pressure simultaneous-ly at two spaced apart points. The assembly inclues a por-tion of a support member (14) which has two parallel sides and a passage connect-ing the two parallel sides. A tubular shaped sleeve (22) is received within the passage and includes short tabs ex-tending slightly past the sur-face of the two parallel sides of the support member. A U-shaped anti-turn bracket (30) is slidably received around the support member and in-cludes slots that coincide with the passage in the sup-port member. The tubular sleeve has a non-circular in-side cross section. A double-ended bolt (26) having a first and second threaded end and an intermediate non-circular portion complementary to the non-circular cross section of the sleeve is slidably received within the sleeve. The bolt is permitted to move linearly but not permitted to rotate within the sleeve. Threaded nuts (138, 142) are placed on each of the first and second threaded end. A uniform torque at both of the first and second ends can be obtained by tightening only one of the nuts without requiring the other nut to be held or tightened. This is accomplished by the ability of the bolt to slide linearly within the sleeve while being prevented from rotating.
