Title: 共に動く移動体トランシーバ装置のグループのための通信制御回路と方法
IPC: H04W84/00
Filed: 1997-04-25
Abstract: (57)【要約】
移動体トランシーバ装置（２８）のグループが共に進む、多ユーザの無線通信システム（１０）（例えばセルラ通信システム）用の制御回路（４２）とその関連の方法（２２０）である。回路（４２）は移動体トランシーバ装置（２８）のグループと共に進み、移動体トランシーバ装置（２８）のグループ全体の動作を制御するための共通制御要求を生成する。セルラ通信システム（１０）で実現すると、移動体トランシーバ装置（２８）のグループ全体のための共通ハンドオフ要求が生成され、各トランシーバ装置はハンドオフ要求を独立に生成する必要はない。移動体トランシーバが、通信を行う相手の固定位置トランシーバと異なる無線インターフェース標準に従って動作する場合は、変換器が通信信号を変換するので通信信号を送ることができる。

Title: Medicament delivery device includes a reservoir, driving means and a hollow needle which extends through the periphery of the skin contacting surface
Inventor: GROSS JOSEPH
IPC: A61M37/00
Filed: 1996-08-30
Abstract: A medicament delivery device (10) has a reservoir within a housing (11) and means for driving medicament from the reservoir. The device is provided with a filling mechanism upon which a medicament container (19) sealed by a penetrable stopper (25) is mounted. The mechanism comprises an internal bore (20) which accommodates an internal rod (21) from which a needle (22) projects. Needle (22) is hollow and is in communication with the reservoir. In order to fill the reservoir, the container (19) is pressed into the bore (20), causing the needle (22) to pierce the stopper (25), the stopper abutting against the rod (21) and acting as a piston to drive medicament from the container (19) as the container (19) is pushed into the bore (20) and moves relative to the stopper (25). Thus, the reservoir can be filled with the sterile medicament which is stable when stored in the container (19), and the filling is easily accomplished without the use of a syringe. A further advantageous feature is provided by a delivery needle which is mounted on the periphery of the lower surface of the housing. This configuration allows the driving means to be located adjacent to the skin, thereby, providing a more stable temperature and more predictable operation of the device.

Title: Staggering identical cohesive pattern form via offsetting
Inventor: PARKER REBECCA L
IPC: B31B41/00
Filed: 1998-06-22
Abstract: Specialized sheets, for example, in the construction of business forms, having patterns of pressure activated cohesive are constructed so that all the sheets can be identical yet when the sheets are in a stack blocking of the pressure activated cohesive, and subsequent feeding problems, are eliminated by making the cohesive patterns offset a dimension "d" perpendicular to the direction of feed of the forms from a feed bin through an imaging device to an output tray.  Either the feed bin, or an edge guide of the output tray, can be shifted at least the dimension "d" to automatically align the pressure activated cohesive patterns on cooperating first and second sheets, and after proper alignment of the cohesive patterns the sheets may be fed through a conventional pressure sealer.  An inserter may be provided for inserting a confidential information sheet between the cohesive pattern-containing sheets, and/or confidential information may be imaged on the inside faces of the sealed packet formed by the sheets using a non-impact printer or facsimile machine.

Abstract: Instrumentation and methods for performing charged coupled device (CCD) based confocal spectroscopy with a laser spot array are provided. A sample is scanned by a plurality of excitation laser scanning spots. The scanning spots are generated, for example, by converting a laser excitation beam into an array of beams using a multiple beam generating optic, such as a Damann grating. Each scanning spot scans and excites a separate region of the sample. Fluorescent light emitted by the sample is collected and imaged onto the surface of a CCD detector that has been electronically divided into bins of pixels, with each bin corresponding to one of the scanning spots. Each bin functions as a confocal aperture in which the confocal depth of focus can be controlled by changing the dimensions of the bin. Plural CCD detectors can be used for multichannel imaging of individual wavelengths. The instrumentation and methods are useful in any spectroscopic application including microscopy and microvolume laser scanning cytometry (MLSC).
