Abstract: A toy for launching ring airfoils comprises a member (58), a ring airfoil support (60) mounted on the member, and a propelling element (62) for moving the support along the member from a first to a second position. The ring airfoil moves with the ring airfoil support as the ring airfoil moves; as the support decelerates at the second position, the ring airfoil is launched forward. The member may include a helical channel (68) which receives a pin (78) attached to the support to impart spin to the support and ring airfoil. The toy may include a protective housing (32), a return element (34) to move the support to a launch-ready position, and a trigger (28) to release the support for forward movement. Components of the toy may be designed so that the characteristics of the ring airfoil at launch are within certain safety limitations.

Title: Gold-plated electrosurgical instrument
Inventor: URUETA R WILFRIDO
IPC: A61B18/14
Filed: 1997-06-27
Granted: 2005-11-22
Abstract: An electrosurgical instrument and method for making and using the same, is provided. The electrosurgical instrument includes a stainless steel blade (18) having two major opposed surfaces (20a, 20b) connected by two edge surfaces (22a, 22b) with each surface plated with an intermediate layer (24), comprising a substantially nontoxic metal having a hardness of at least about 130 on a Knoop scale, and an electrical resistivity not exceeding about 15 microhm-cm at 20 degrees Celsius. A non-stick coating (28) is coated on either all of the surfaces of the intermediate layer, or only on the two major opposed surface s, thereby exposing the two edge surfaces of the intermediate layer in the latter case. The non-stick coating prevents tissue from stickin g to the instrument during surgery, while the intermediate metal layer enhances the electrical conductivity of the instrument for more efficient cutting and cauterization of tissue with less power consumption. The combination of an intermediate metal layer with an outer non-stick coati ng eliminates the need to choose between quick and efficient cauterization during surgery, and the prevention of tissue sticking to the instrument.

Abstract: A digit splint is defined by an arcuate angularly inclined base and an ovoid which extends upwardly and radially outward from the base. The base is positioned on the palmar side of a joint of a digit and the ovoid conforms to the dorsum of a digit when the digit is in an extended position without hyperextension. The ovoid has two substantially parallel sides which, when worn, conform to impinge on the sides of the joint of a digit at the axis to provide lateral stability at the joint of a digit and to prevent migration of the splint on a digit. The splint also prevents hyperextension of the joint of a digit. In an alternate configuration, the splint may be rotated 180 degrees about the horizontal axis on a joint of a finger. In this configuration, the splint provides lateral stability at a joint of a digit and corrects flexion at a joint of a digit.

Title: Systemes de controle pour arcs electriques
Inventor: BENOIT LUC PIERRE
IPC: H01T1/12
Filed: 1997-08-14
Granted: 2004-06-22
Abstract: On contrôle les arcs électriques en exploitant la découverte selon laquelle les arcs électriques sont des phénomènes fractals, toutes les informations essentielles qui signifient "arc" étant contenues dans chaque sous-ensemble fractal. Ces sous-ensembles fractals sont distribués d'une manière logarithmique sur l'ensemble du spectre de l'arc. On effectue de la manière la plus avantageuse le contrôle des arcs sur un sous-ensemble fractal d'un ordre logarithmique faible, dans lequel l'amplitude est supérieure du fait de la caractéristique 1/f des arcs (22), l'induction croisée entre circuits voisins est plus faible et le trajet entre l'arc et le point de détection de la signature de l'arc (23) est plus long qu'aux hautes fréquences utilisées habituellement pour la détection d'arcs. La transformation du sous-ensemble réduit le risque de fausse alarme. Les différentes parties d'une signature d'arc peuvent être traitées dans des voies déphasées ou comme des porteuses modulées.

Abstract: A method and system for managing process requests between and application program and an operating systems managing processes. Process requests and, in particular, file locking or unlocking requests from an application program written on one operating systems may causes files to be corrupted if the application program is ported to a new operating system without rewriting portions of the program code. A file locking emulator is used between an application program and an operating system. The file locking emulator comprises an application program interface and a file lock supervisor. The file locking emulator receives the file locking requests from the application program and generates file requests and file lock query commands. When the application program interface receives a file request it first checks the files lock status and then either returns an error for incompatible file requests or executes the compatible lock request along with any other compatible operation request such as a read, write or truncate file operation. Incompatible file locking requests return an error statement which may include error recovery options available to a user of the application program. The status of files accessed by the application program are stored in file lock managers. Only code in the file request emulator needs to be rewritten when an application program is ported to different operating systems sharing incompatible but executable processes. In this manner tested code of the application program does not have to be rewritten.

Abstract: A holder for mounting a wiper mop to the end of a handle and for clamping a number of relatively movable, absorbent strips (28, 29) of a textile material essentially transverse to the longitudinal axis of the handle. The holder has a head part and a plate for clamping the strips therebetween. In the strip clamping region, the holder has a base surface which has a larger length than width. The outer edges of the base surface are curved without a change in the direction of curvature to form a pair of corners (6, 7; 26, 27). The sectional change in the curvature on connection with the corners is especially good for cleaning of hard to reach locations. The corners are rounded at a radius of 0.05 to 0.25 the width of the holder which allows a rolling-off movement past the corner.

IPC: H05B44/00
Filed: 2001-04-27
Granted: 2004-06-22
Abstract: When charging at a voltage with a polarity different from that of a voltage charged in the capacitive display element, by turning the switch ON, after carrying out a charging/discharging to modulate both electrodes of the capacitive display element to the ground potential, the same is charged at a voltage with another polarity.  As compared with the case where the charging/discharging between the positive power supply voltage + V M and the negative power supply voltage - V M is made directly, the electric power consumption can be reduced to 1/2 when the same is once modulated to the ground potential 0V.  The electric power consumption can be further reduced by modulating the intermediate potential in a plurality of steps.
