Abstract: The current invention relates to a method and a device for converting a random number sequence into carrier frequencies fx for mobile radio transmission. A  shift register (25) with a register content of n bits is provided. The register content is shifted by 1 bit, whereupon a decision is made as to whether the value of a number of k bits of the register content is greater than the overall number Y of possible carrier frequencies fx, whereby k is less than or equal to n. If the decision is positive, the value of the k bits is used to select the next carrier frequency fx. The carrier frequency is selected, for instance, from a table in which the possible carrier frequencies are allocated to certain positions. The inventive method and the inventive device can be carried out and used in a mobile radio device in an easy, reliable and economical manner.

Title: Hypodermic syringe having a selectively retractable needle
Inventor: BELL JON S
IPC: A61M5/32
Filed: 2001-05-18
Abstract: A syringe includes an elongate barrel having an open proximal end and a distal end that includes a fitting. It also has a plunger having a proximal end and a distal end, sized for slidable movement within the barrel thereby defining a chamber within the barrel. The plunger also has an elongate cavity therewithin that has a closed proximal end and an open distal end. The open end of the plunger is closed by a selectively releasable closure. The syringe has a hub that attaches to the barrel with a fitting conjugate to the fitting. The hub includes an elongate needle having a proximal end, a distal end and a fluid path therethrough. The needle is positioned in the passageway for slidable movement between a first position wherein the fluid path of the needle is in fluid communication with the chamber and a second position. The needle has a mount at its proximal end forming a seal with the chamber when the needle is in the first position. The syringe has a spring disposed about the mount biased to urge slidable movement of the needle from the first position. The syringe includes a latch disposed in the hub to engage the mount and retain the mount in the first position. The latch is releasable so that the spring urges the needle to move from the first into the second position within the cavity in the plunger, once the latch is released.

Abstract: L'invention concerne un procédé et un appareil (10) conçus pour le compostage de matières premières comme les matières organiques, mais aussi des matières toxiques et dangereuses, par le maintien de conditions de compostage dans des limites prédéfinies. Un conteneur (20) hermétique comporte une chambre isolée possédant une base avec un puits gravitaire (27), un plancher plat perforé (26) définissant un petit espace de drainage pour l'air et le lixiviat entre le plancher et la base, et des conduits d'entrée et de sortie d'air. Des clapets (44 et 48) régulent le flux d'air et d'autres gaz en fonction de certaines conditions ou de détecteurs. Selon le procédé, la composition de la matière organique est modifiée et/ou inoculée, suivant les besoins, pour transformer la matière première en un mélange compostable. L'incubation produit un mélange de compostage à partir du mélange compostable. Le procédé consiste à surveiller et à ajuster les conditions du mélange de compostage afin de maintenir les conditions dans des limites prédéfinies. Les conditions du mélange de compostage sont réglées en aérant le mélange de compostage ou en mélangeant à nouveau ledit mélange. Le matériau de compostage à nouveau mélangé est incubé pour produire une matière organique compostée. L'invention touche à différents systèmes utilisant des conteneurs hermétiques conçus pour fonctionner avec l'équipement de manutention existant, comme par exemple, les chariots à fourche, les chariots à manutention horizontale et les équipements combinés.

Title: Health monitoring and diagnostic device and network-based health assessment and medical records maintenance system
Inventor: MAUS CHRISTOPHER T
IPC: G16H10/60
Filed: 1999-11-08
Abstract: A health monitoring and diagnostic device (LIFESTREAM cholesterol meter) configured as a self-contained testing and diagnostic unit in a clam-shell type case. One side of the case includes a spring-loaded finger stick and a compartment for carrying one or more packages of disposable items including a test strip, a needle for the finger stick, and an alcohol swipe. The other half of the case includes a test strip reader, a key pad, and a liquid crystal display.    The meter reads a test strip carrying a droplet of blood and receives additional diagnostic information from the patient, such as age, gender, weight, and family history of heart disease. Within minutes, the meter displays test results, including total cholesterol levels. The meter also displays additional diagnostic results, such as the patient's "cardiac age", recommended weight loss, and a cardiac risk assessment. The meter also works in connection with a network-based comprehensive health analysis and reporting system. The meter writes patient data to a smartcard. This patient data typically includes patient identification information, the test results, the diagnostic information, and the diagnostic results. A computer station reads the smartcard and establishes a network connection with a health report server over the Internet. The computer then downloads the patient data to the health report server, which prepares a comprehensive health report. Within minutes, this report is transmitted back to the computer station, where it is printed out and delivered to the patient.
