Granted: 2011-06-21
Abstract: Disclosed is an electrochemical sensor for the determina- tion of analytes in body fluids, e.g. glucose in blood. The sensor involves a non-conductive base which provides a flow path for the body fluid with the base having a working and counter electrode on its surface which are in electrical com- munication with a detector of current. The base and a cover therefore provide a capillary space containing the electrodes into which the body fluid is drawn by capillary action. The counter electrode has a sub-element which contains an electro- active material and is configured in the system (sensor and meter) to provide an error signal when insufficient body fluid is drawn into the capillary.

Title: Detachable accessory holder
Inventor: HOLSTEN STUART V
IPC: A47L9/32
Filed: 2003-04-30
Granted: 2011-06-21
Abstract: The present invention provides a holder for storing accessories on a wet/dry vacuum. The holder securely attaches to the vacuum and readily detaches therefrom. The detachable holder may be detached with the accessories. While an operator dumps debris out of the drum of the vacuum, detaching the holder prevents the accessories from being inadvertently spilled out of or discarded from the holder. The detachable accessory holder fully secures to a bracket attached to the vacuum. The secure attachment prevents the holder from falling off or tipping on the vacuum. To attach the holder to the bracket and vacuum, grooves on the holder are set on to an axle of the vacuum. As the holder is pivoted about the axle, tabs and a latch on the holder engage slots and a step on the bracket. To remove the holder, the operator presses on the latch and lifts the holder from the bracket and the appliance.

Granted: 2008-12-23
Abstract: L'invention concerne un procédé continu permettant de séparer des composants de graines de lin. Les graines de lin sont séchées jusqu'à atteindre un degré d'humidité compris entre environ 0,5 % et environ 3,0 %, puis introduites dans une chambre de séparation comprenant un rotateur abrasif. Lorsque les graines de lin passent sur le rotateur abrasif, le contact avec le rotateur sépare les composants des graines de lin en pellicules et grains. Les pellicules et les grains sont séparés et peuvent être utilisés sous cette forme ou traités de façon plus approfondie. Les pellicules peuvent être traitées de façon plus approfondie par extraction à l'aide d'eau et d'hexane afin de retirer, respectivement, la gomme et l'huile des graines de lin. Ces deux extractions peuvent être effectuées dans n'importe quel ordre. Le procédé selon l'invention permet d'obtenir un composant de graines de lin riche en lignane, un extrait de gomme et de l'huile. Ces composants séparés de graines de lin peuvent être utilisés dans des produits tels que des produits alimentaires, des produits de soins personnels ou des nutraceutiques.

Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software. The device provides output in the form of a default output and a number of variants. The output is based largely upon the frequency, i.e., the likelihood that a user intended a particular output, but various features of the device provide additional variants that are not based solely on frequency and rather are provided by various logic structures resident on the device. The device enables editing during text entry and also provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. Additionally, the device can facilitate the selection of variants by displaying a graphic of a special <NEXT> key of the keypad that enables a user to progressively select variants generally without changing the position of the user's hands on the device.
