Patent CA-2179580-A1 (CA)
Inventor: DANIELSON ARVIN D
IPC: G06F1/3293
Filed: 1996-06-20
Abstract: A portable data collection terminal has an elongate housing with a hand grip conforming rear surface. A front surface features a numerical keyboard adjacent a lower end of the housing and an LCD screen adjacent the keyboard toward an upper end of the housing. The display screen is of elongate rectangular shape, its length extending longitudinally of the housing of the data terminal. The active area of the display screen is covered by a touch sensitive overlay screen which is configured in one mode of operation of the data terminal into an alphabetical keyboard. The orientation of the display is switchable between orientation in which the line direction of the displayed data extends across or longitudinally of the data terminal. The keys of the numerical keyboard are identified by indicia disposed on a template. The orientation of the template may be sensed to switch the orientation of the displayed data and touch sensitive key identifiers to correspond to the orientation of the indicia on the template. As a further embodiment an electromagnetic activation by a pen may be used to enter data into a data terminal. Power saving shutdown extends the battery life of the data terminal. A shutdown mode permits resumption of operations by depression of a key. During operations power consumption is reduced by efficient distribution of operations control between microprocessors. The microprocessors have shared access to and control of system operations.

Title: Adjustable Vending Mechanism
Inventor: ODEN KENNETH W
IPC: G07F11/04
Filed: 1997-03-14
Abstract: An adjustable mechanism for vending products includes left and right column walls defining a column divided into front and rear sections for retaining the products in front and rear corded stacks. A rear spacer provided at the back side of the column is laterally adjustable relative to the front side of the column to accommodate products of different lengths in the rear section. Front and rear product funnels are positioned respectively in the front and rear sections above the bottom end of the column, with front and rear adjustable product ramps interposed between the outlets of the front and rear product funnels, respectively, and the open bottom end of the column. The front and rearadjustable product ramps are independently pivotable about their pivot axes in response to movement of front and rear adjustment rods to change the width of the open bottom of the column at the front and back sections to accommodate products of different diameters. Front and rear rotatable cradles are positioned below the outlets of the front and rear product funnels, respectively, to releasably support the bottommost products in the front and rear corded stacks, and are independently rotatable to vend products independently from the front and rear stacks. The cradles are rotated by front and rear motors drivingly connected to the front and rear rotatable cradles, respectively. The front and rear adjustment rods each have a forward end formed into a handle which extends forwardly of the front side of the column through a cover plate covering the front side of the column. The cover plate includes a gauge thereon indicating positions of the handles corresponding to preselected product sizes. The cover plate can further include a size gauge for measuring the size of an article.

Patent CA-2203898-A1 (CA)
Inventor: SIEFFERT KENT J
IPC: H04N19/00
Filed: 1995-10-10
Abstract: La présente invention concerne un système d'imagerie médicale destiné à communiquer des informations sur des images entre plusieurs appareils imageurs d'entrée différents, ayant différents protocoles d'entrée, et plusieurs appareils d'imagerie de sortie différents, et qui tire parti d'une architecture réutilisable de logiciel qui possède plusieurs éléments constitutifs indépendants en ce qui concerne le fonctionnement. Ces derniers peuvent être configurés pour former une conduite de communication ("pipeline") servant à communiquer des informations sur des images entre un appareil imageur d'entrée et un appareil imageur de sortie, en fonction des protocoles désirés. Chaque élément constitutif est interchangeable avec un élément d'une configuration différente, afin de faciliter la communication d'informations sur les images conformément à un protocole différent, ce qui change la configuration de la conduite, donnant une souplesse importante. De plus, l'architecture du logiciel peut être réalisée à une échelle permettant de produire plusieurs conduites de communications dont chacune peut être configurée conformément à des protocoles désirés. Ainsi, le système de la présente invention peut supporter un protocole différent soit par échange d'éléments constitutifs pour reconfigurer une conduite de communication unique, soit par le choix d'une autre solution parmi plusieurs conduites de communications aux configurations différentes, dans l'architecture pouvant être mise à l'échelle. Du fait que chacun des éléments constitutifs est isolé et indépendant en ce qui concerne son fonctionnement, s'il est nécessaire de changer la conception de l'un d'eux, plusieurs programmeurs peuvent être affectés à cette tâche avec peu de travail ajouté par ailleurs, ce qui économise du temps et de l'argent. Le caractère modulaire de l'architecture permet aussi d'effectuer les modifications ou corrections nécessaires sur un seul élément constitutif, avec peu de conséquences sur l'ensemble du système.
