Title: Symbol error based power control for mobile telecommunication system
Inventor: PENG WEI-CHUNG
IPC: H04B7/26
Filed: 1995-10-05
Granted: 1999-12-14
Abstract: A mobile telecommunication system power control loop includes a symbol error rate detector to detect a number of symbol errors induced during transmission, asumming node to subtract the output of the symbol error rate detector from a symbol error rate target, a multiplier to introduce an adjustment factor, and an integration element to sum the output of the multiplier with past outputs of the multiplier. The output of the integration element is a signal power to noise power ratio target which is used to control the transmission power of the mobile telecommunication system. In one embodiment the symbol error rate target is a constant or parameter set by the user. In another embodiment the symbol error rate target is adjusted automatically to maintain a constant frame error rate.

Abstract: A dual entrance window ion chamber is provided for purposes of measuring x-ray exposure.  The ion chamber includes a housing having a cavity formed therein and which defines an ion chamber.  The housing has oppositely disposed first and second openings therein located on opposite sides of the chamber.  First and second x-ray entrance windows respectively cover the first and second openings for permitting entrance of x-rays into the chamber.  A collector is located in the chamber intermediate the first and second windows for collection of electrons for use in measuring x-ray exposure.  The first and second windows are constructed differently from each other such that the first window is optimized so that the ion chamber provides a relatively flat energy response to x-rays over a first x-ray energy range.  The second window is optimized so that the ion chamber provides a relatively flat energy response over a second x-ray energy range.  The second energy range is of a greater energy level than that of the first energy range.

Title: Electrostatic spray appliance for coating material
Inventor: BUSCHOR KARL
IPC: B05B5/03
Filed: 1996-06-26
Granted: 1999-08-31
Abstract: Electrostatic spray device for coating powder or liquid with at least one charging electrode for electrostatic charging the coating material. The device has at least one, and preferably a plurality, of counter electrodes for the electrostatic removal of free charges (electrons or ions) from the stream of sprayed coating material adjacent a coating material discharge nozzle on the device. The counter electrodes are carried by a ring which is slipped onto a body of the device. A sleeve screwed onto the body holds the ring in an axial direction on the body. An electrical line for discharging the free charges from the counter electrodes is secured to the ring. The electrical line passes through and is confined in a bore in the body to prevent rotation and axial movement of the ring on the body. When the sleeve is removed from the body, the counter electrode ring and attached electrical line can be withdrawn from the body in the axial direction as a unit.

Abstract: Modified oligonucleotides 3'-NHP(O)(O-)O-5' phosphoramidates were synthesized on a solid phase support. The phosphoramidate analogs were found to have significantly increased resistance toward phosphodiesterase digestion. Thermal dissociation experiments demonstrated that these compounds form more stable duplexes than phosphodiesters with complementary DNA and particularly RNA  strands. Further, the phosphoramidate analogs can also form stable triplexes with double-stranded DNA target, where under similar conditions parent phosphodiester compounds failed to do so.

Title: Determination simultanee du nombre de bacteries e. coli et du nombre total de coliformes
Inventor: CHANG GEORGE
IPC: C12Q1/10
Filed: 1995-04-26
Granted: 2002-06-18
Abstract: La méthode générale proposée consiste à mettre en contact une colonie de bactéries avec un substrat de .beta.-D-galactosidase et une source de carbone (par exemple adonitole, esculine, salicine, amygdaline, cellobiose, etc.) pouvant être métabolisés par une pluralité d'espèces de coliformes mais qui ne peuvent pas être métabolisés par E. coli, et à détecter les signaux de produits de réaction, provenant du substrat et de la source de carbone. L'absence des deux signaux des produits de réaction indique la présence de bactéries non coliformes; la présence des deux signaux des produits de réaction indique la présence de bactéries coliformes qui ne sont pas de l'espèce E. coli; et la présence du signal du produit de réaction du substrat de .beta.-D-galactosidase et l'absence du signal de produit de réaction de la source de carbone indiquent la présence de bactéries E. coli. Un signal peut permettre d'identifier un produit de réaction en soi (par exemple un produit coloré dérivé d'une forme chromogène du substrat ou d'un réactif chromogène qui interagit avec le produit, etc.), ou bien en effet de produit de réaction sur la colonie ou au niveau de celle-ci (par exemple répression catabolique, croissance, variation localisée du pH, etc.). Selon un mode préféré de réalisation, le signal du produit de réaction du substrat de .beta.-D-galactosidase est produit directement par un produit de réaction de .beta.-D-galactosidase, et le signal du produit de réaction de la source de carbone est produit par répression catabolique du signal du produit de réaction du substrat de .beta.-D-galactosidase, répression qui est induite par le produit de réaction de la source de carbone, au niveau d'une partie de la colonie.

Abstract: Corps de chauffe à air frais comportant un corps (2) contenant une voie d'écoulement (25) d'air vicié et une voie d'écoulement (14) d'air frais. Des dérivés de gaz obtenus après combustion provenant d'un brûleur à gaz (29) sont mélangés avec l'air frais pour réchauffer celui-ci à une température souhaitée avant qu'il ne soit évacué dans une enceinte. Les deux voies s'étendent à travers un échangeur de chaleur (15) et le débit de circulation d'air vicié déplacé par un ventilateur (26) à travers le corps est sensiblement égal à celui d'air frais déplacé à travers ce même corps par un second ventilateur (21). Comme le débit de circulation d'air frais provenant du corps et introduit dans une enceinte correspond sensiblement à celui de l'air vicié provenant de l'enceinte, et comme la chaleur est transférée entre les deux écoulements d'air par l'échangeur de chaleur (15), un remplacement total de l'air dans l'enceinte à un rythme relativement soutenu peut être supporté d'une manière économiquement viable. La teneur en produits de combustion nocifs dans l'enceinte et la teneur en produits générés par le brûleur à gaz (29) peut ainsi être maintenue en-deçà des valeurs considérées comme nuisibles par les autorités sanitaires.
