Title: System for effecting actions over vertical surfaces
Inventor: MORAN THOMAS P
IPC: G06F3/033
Filed: 2000-11-22
Abstract: The Pendulum Whiteboard Printer is a fully-automatic robotic device for marking or otherwise effecting whiteboards, pinboards, or other vertical surfaces.      The physical device consists of an effector platform suspended by two suspension wires whose lengths are adjusted by motorized spindles mounted above and on either side of the board surface. The position of the effector platform is adjusted by winding and unwinding the wires. Electrical power is supplied to the effector platform through the suspension wires or through an on-board battery. Control of a pen and/or other apparatus on the effector platform is achieved through modulation of the power voltage. A further component of this invention is electronic and computational apparatus for controlling the device, which may include automatic visual interpretation and feedback from a video camera viewing the board and printer.

Title: Method for starting a fuel cell system, as well as a fuel cell system
Inventor: STUHLER WALTER
IPC: H01M8/04223
Filed: 1999-04-19
Abstract: The invention relates to a method for starting a mobile fuel cell system, in particular for a vehicle, in which the air which is to be supplied to the system is conveyed during starting and operation of the system by a motor-powered compressor (2), in order to ensure the necessary operating pressure and, if required, additional humidifying of the air. The motor drive for the compressor (2) has an electric motor (4, 20) which is supplied from a mobile starter battery (5) during the starting phase. The output voltage of the starter battery (5) is different to the operating voltage at the output of the fuel cell stack (1) of the fuel cell system, with a control device (10) being provided between the output of the starter battery (5) or of the fuel cell stack (1) and the motor input (8), which control device (10) interrupts the starting voltage supplied from the output (6) of the starter battery (5) and switches over to the output voltage of the fuel cell stack (1) when the output operating voltage of the fuel cell stack (1) reaches an adequate level.

Title: Large nxn optical switch using binary trees
Inventor: DRAGONE CORRADO
IPC: H04B10/29
Filed: 2001-10-02
Abstract: A dilated N × N optical cross-connect switch suitable for large N  exhibits good efficiency (element count) without a significant increase in and reduced small depth (low loss) and crosstalk. The present arrangement consists of six levels of binary trees of 1 × 2 and 2 × 1 elements. The first two levels form the input stage, the third and fourth levels form the center stage, and the fifth and sixth levels form the output stage. In each of the input, center, and output stages, the odd number level is formed as a binary tree of 1 × 2 elements and the even numbered level is formed as a binary tree of 2 × 1 elements. Each stage is formed by directly joining together the 1 × 2 element binary tree with the 2 × 1 element binary tree. In one embodiment, depth is substantially reduced by using a symmetric arrangement of one or more 2×2 elements located in the vicinity of each junction between adjacent stages. The arrangement also features reduced depth obtained by a Clos type construction.

Title: Lcm (laser capture microdissection) for cellular protein analysis
Inventor: SIMONE NICOLE
IPC: G01N1/30
Filed: 2000-02-16
Abstract: The present invention describes devices and methods for performing protein analysis on laser capture microdissected cells, which permits proteomic analysis on cells of different populations. Particular disclosed examples ar e analysis of normal versus malignant cells, or a comparison of differential protein expression in cells that are progressing from normal to malignant. T he protein content of the microdissected cells may be analyzed using techniques  such as immunoassays, 1D and 2D gel electrophoresis characterization, Wester n blotting, liquid chromatography quadrapole ion trap electrospray (LCQ-MS), Matrix Assisted Laser Desorption Ionization/Time of Flight (MALDI/TOF), and Surface Enhanced Laser Desorption Ionization Spectroscopy (SELDI). In additi on to permitting direct comparison of qualitative and quantitative protein content of tumor cells and normal cells from the same tissue sample, the methods also allow for investigation of protein characteristics of tumor cells, such as binding ability and amino acid sequence, and differential expression of proteins in particular cell populations in response to drug treatment. The present methods also provide, through the use of protein fingerprinting, a rapid and reliable way to identify the source tissue of a tumor metastasis.
Patent CA-2359784-A1 (CA)
Title: Multi-functional stalk switch
Inventor: RIGSBY BRUCE S
IPC: B60Q1/14
Filed: 2001-10-23
Abstract: A multi-function stalk switch that incorporates a pushbutton switch, a first rotary switch and a second rotary switch onto the end of a stalk, wherein further switching functions may be executed by moving the entire stalk in either of two orthogonal planes. The stalk switch incorporates many design features that enable it to be assembled at low cost from a small number of parts. One such feature is the use of plastic-on-plastic detents to control positioning of the rotary switches so that they wipe across predetermined portions of a flexible printed circuit board.  Another feature is the inclusion of a springloaded plunger detent riding in a concave centering mechanism that is operable to automatically return the stalk switch to its central (neutral) position after removal of external biasing forces. A further feature is the inclusion of magnets on the stalk switch and Hall effect sensors fixedly mounted nearby in order to sense movement of the magnets (and therefore the stalk) in two orthogonal planes. Further features of the invention are also disclosed.

Patent CA-2367114-A1 (CA)
Inventor: TAPPER ROBERT
IPC: A61N1/32
Filed: 2000-03-16
Abstract: A sweat control or hyperhidrosis treatment device (10) for providing iontophoresis of antiperspirant into a region of a human body includes a DC  power source (28), a controller and a pair of electrodes (12, 24). The electrodes are mounted in generally close proximity to one another and are separated by an insulating member (18). The electrodes generally carry an antiperspirant element and are responsive to a current signal through the controller. The electrodes are generally formed of aluminum and have a rough surface to increase the number of aluminum ions available for infusion into the region. The controller converts the DC signal to an AC wavform. The device further includes a pair of pads (22, 24). Each of the pads is positioned in adjacent contact with one of the electrodes and preferably carries sodium salicylate to increase the permeability of the region.
