Title: Spectrally efficient digital fm modulation system.
Inventor: LEITCH CLIFFORD DANA
IPC: H04L27/14
Filed: 1990-07-09
Abstract: A method is described for transmitting digital data with minimum splatter and for recovering the same with a conventional frequency modulated (FM) receiver to obtain data having minimum intersymbol interference. The method utilizes an optimized prototype pulse which has been predistorted to match the inverse characteristics of the post detection low pass filter in a conventional FM receiver. When the optimized electric pulse is received and processed by the post detection low pass filter of the conventional FM receiver, a pulse shape exhibiting minimal intersymbol interference is produced.

Inventor: MIYAKAWA TSUTOMU HOKUTO MANUFA
IPC: H02J7/14
Filed: 1993-10-13
Abstract: Un circuit de commande intervient sur des batteries chargées en parallèle par un générateur. Une difficulté fréquente provient de la décharge d'une batterie classique, le démarreur ne pouvant alors lancer le moteur et le véhicule, une automobile par exemple, restant immobilisé. Un véhicule est donc doté de deux batteries chargées en parallèle par un générateur. Quand la clé de contact n'est pas sur la position démarrage, l'énergie utilisée par la charge provient de l'une ou l'autre de ces batteries. Quand la clé de contact est sur la position démarrage, l'énergie est fournie en parallèle par les deux batteries au démarreur du moteur et à la charge, et la batterie connectée à la charge est commutée sur l'autre batterie.

Title: Fluid sample receptacle
Inventor: MEADOR JAMES W
IPC: A61J1/05
Filed: 1994-03-08
Abstract: A fluid sample receptacle provides a means of assuring uncontaminated, multiple samples of a fluid specimen. An upper or isolated sample chamber (10) and a lower or primary sample chamber (12) provide redundant test samples. A cover or lid (27) with a downwardly extending column (30) includes a stopper (34) with a removable plug (36) attached to automatically seal the lower sample chamber when the cover is sealed across the top of the upper chamber. This feature guarantees that the samples chambers are sealed or isolated simultaneously and that the test samples are therefore identical when taken. Tamper evident seals (17) prove that either sample has not been contaminated. A preferred embodiment provides a bellows assembly (90) to accommodate variations in ambient pressure and to provide a positive means of expelling a precise quantity of fluid from the receptacle for testing.

Title: Needleless injection site
Inventor: MAYER BRUNO FRANZ P
IPC: A61M39/04
Filed: 1996-04-18
Abstract: A needleless injection site comprising a housing which defines an interior chamber and a central opening which communicates with the interior chamber. The housing further defines a proximally extending dilator projection portion which is co-axially aligned with the central opening and a distally extending adapter portion. The dilator projection and adapter portions define a continuous fluid passage. Disposed within the central opening and the interior chamber is a reseal member which has an elastically openable and closable aperture formed therein. The reseal member normally resides in a first position within the housing wherein the aperture is in a closed configuration. The reseal member is deformable such that the application of distally directed pressure thereto will cause the reseal member to distally advance within the housing to a second position wherein the aperture assumes an open configuration and communicates with the fluid passage. The cessation of the application of distally directed pressure to the reseal member will cause it to resiliently return to the first position wherein the aperture reassumes the closed configuration.
