The invention relates to a method of identifying a plurality of transponders each of which transmits data at intervals to a receiver. The invention also relates to an identification system comprising a plurality of transponders and a receiver, to the transponders themselves and to an integrated circuit for use in a transponder. The transponder repeats data to the receiver at random or pseudo-random intervals in length. The intervals are directly or indirectly dependent on the output signal from a counter responsive to a physical characteristic of the transponder.

The specification describes the use of selected DPP IV inhibitors for the treatment of physiological functional disorders and for reducing the risk of the occurrence of such functional disorders in at-risk patient groups. In addition, the use of the above-mentioned DPP IV inhibitors in conjunction with other active substances is described, by means of which improved treatment outcomes can be achieved. These applications may be used to prepare corresponding medicaments.

Uses of DPP-IV inhibitors

PROBLEM TO BE SOLVED: To enable each vehicle to safely and smoothly run autonomously by making a road-side controller and each vehicle requiring avoidance perform the most suitable obstacle avoiding operation in cooperation with each other. SOLUTION: Information of an obstacle detected by a running vehicle MS1 and information of the obstacle detected by a road-side sensor LS are exchanged through an road-vehicle communication system consisting of a road-side machine BSi and a radio machine on the vehicle, and a centralized base station CS2 generates avoidance indication information based on both detected information. The avoidance indication information is reported to vehicles MS1 and MS2 requiring the avoiding operation through the road-vehicle communication system, and thus the vehicle MS1 performs the avoiding operation.

PROBLEM TO BE SOLVED: To provide an information terminal equipment in which the comparison between pages is easily performed and the edition for every page becomes easy. SOLUTION: The liquid crystal boards 1 to 3 of a portable type information terminal 14 have at least one of means displaying the information file composed of at least one of character information, graphic information and image information and means inputting and editing the information file. The boards are provided with communi-cation means transmitting and receiving the information file and control information and means for cooperating with other information terminal equipments by using this communication terminal. At least one information file is displayed by dividing the file between other cooperative information terminal equipments.

PROBLEM TO BE SOLVED: To provide a stabilized composition of teprenone. SOLUTION: This stabilized teprenone composition contains teprenone, and glycine or contains teprenon, glycine and manitol. By the addition of glycine, the formation of decomposition product of teprenone under conservation is suppressed and further, by using manitol, the coloration change in appearance can be prevented.

Stabilized teprenone composition, and stabilizing method

PROBLEM TO BE SOLVED: To provide highly precise road information by exactly and dynamically obtaining the situation of a road without setting plural fixed sensors. SOLUTION: A mobile monitoring device equipped with an image pickup camera is loaded on each of plural existing vehicle MS1-MSn for tasks, and a road video image picked-up by the image pickup camera and position information detected by using a GPS are transmitted by radio through a mobile communication network MNW to a road information control sensor SC. Then, in the road information control sensor SC, the image pickup information is analyzed so that the situation of a road such as traffic jam, traffic control, and weather can be recognized, and the road information indicating the recognized result is mapping-processed on a map based on the position information, and stored in a storage part. Then, when a distribution request arrives from not only the vehicles MS1-MSn for tasks but also general mobile station users PS1-PSm or fixed station users HS1-HSi, the road information corresponding to this request is selectively read from the storage device, and distributed to the origin of request.

PROBLEM TO BE SOLVED: To improve the read performance of identification information and to quicken a processing by setting a time slot number allocated from a controller to a responder to the optimum value of the highest read efficiency when the controller reads the identification information of a plurality of responders. SOLUTION: A time slot management control part 13 provided inside the processing control part 11 of this controller 10 recognizes the response state of time slots from the responders 21, 22,..., 2t received in a transmission/ reception processing control part 12. When a transmission error is present in the identification information (Tag1, Tag2,...) of the responded time slot, The control part 13 estimates the number of the responders 21-2t leaving the information to be read from the response state of the respective time slots, decides a new time slot number from the number of the responders, and specifies the new time slot number and instructs the response for the responders 21-2t leaving the identification information (Tag1, Tag2,...) to be read.
