Abstract: Cette invention concerne une balle sphérique comprenant plusieurs segments qui sont disposés d'une manière sensiblement parallèle l'un par rapport à l'autre, chaque segment étant adjacent à au moins un autre segment, mais pas à plus de deux autres segments. Les segments adjacents sont joints les uns aux autres au niveau d'interfaces sensiblement planes, l'ensemble des segments se composant des éléments suivants: un premier segment possédant une première épaisseur ainsi qu'une première caractéristique de modulation optique; un second segment possédant une deuxième épaisseur ainsi qu'une deuxième caractéristique de modulation optique; et enfin, un troisième segment possédant une épaisseur différente de l'une au moins des première et deuxième épaisseurs, ainsi qu'une caractéristique de modulation optique différente de l'une au moins des première et deuxième caractéristiques. Cette balle possède une anisotropie permettant d'obtenir un moment dipôle électrique, lequel moment rend la balle sensible à l'électricité. Ainsi, lorsqu'elle est mise en rotation dans un champ électrique non oscillant pendant que le moment dipôle électrique se produit, la balle va avoir tendance à tourner selon une orientation faisant s'aligner ledit moment dipôle électrique sur le champ.

Title: Selective electrochemical process for creating semiconductor nano- and micro-patterns
Inventor: SCHMUKI PATRIK
IPC: H01L21/265
Filed: 1998-11-20
Granted: 2007-06-26
Abstract: A porous semiconductor is created by electrochemical etching. Selected regions of a semiconductor are first treated to reduce the threshold potential at which pore formation occurs, and then an electrochemical etch is carried out on the semicnoductor at a potential at least equal to the reduced threshold potential for the selected regions and less than the threshold potential for untreated regions. The selective treatment preferably involves implantation with the same ions as the semiconductor, i.e. Si ions for silicon. The treatment results in the formation of highly defined etch patterns or patterns of porous material depending on the process conditions.

Abstract: Selection of a call for handling by a call-center agent (106-108) is based on which call's handling by the available agent will tend to optimize call-center performance criteria such as efficiency (e.g., minimize per-call handling time) or derived benefit (e.g., maximize revenue). Each agent has a service profile for each type of call that they handle. A service profile (400-402) comprises present values of a plurality of service metrics, such as proficiency, profitability, customer satisfaction, and agent satisfaction. When an agent becomes available, the present values of the service metrics of the service profile (500-502) of that agent for each type (e.g. skill) of available call handled by the agent are combined (610) into a score according to one of a plurality of formulas which corresponds to that call type, and a call of the type for which the agent has the best (e.g., either highest or just-sufficient) score is assigned (612) to the agent.      Preferably, a call score is also computed (807) for each available call type, based on factors such as the purpose of the call, the call's in-queue wait time, the priority of the call, etc. The call type for which the agent has the best score is selected (812) to be the one for which the call score best matches the agent's corresponding score. When the assigned agent finishes handling the call, his or her performance is evaluated (202-206) based on the service metrics, and the valuations are used (210) to revise the present values of the service metrics of that agent's service profile.      The revision process gives (208) more weight to valuations of more-recently-handled calls to reflect both long-term and short-term agent performance trends and variations.

Abstract: An automatic safety system for a fluid fuel air heating furnace. The safety system utilizes a double-sided carbon monoxide sensor for detecting unsafe levels of carbon monoxide interiorly and exteriorly of the furnace's heated air duct and a single-sided carbon monoxide sensor for detecting unsafe levels of carbon monoxide interiorly of the furnace's flue pipe.      The sensors employ carbon monoxide detector chips which are electrically conductive in normal conditions, but become non-conductive when exposed to levels of carbon monoxide that are deemed unsafe for humans. The sensors are incorporated in an electrical circuit for energizing a solenoid valve which valve, when energized, opens to permit fuel flow to the furnace. Detection of unsafe levels of carbon monoxide will result in the sensors becoming non-conductive, thereby causing the solenoid valve to become de-energized and to close thereby preventing fuel flow to the furnace.

Abstract: The invention provides a table horse racing game which imparts much of the fun of actual horse racing. A table frame having lateral and end walls is provided as is a table board which can slide back and forth in grooves provided in the lateral walls. A crank is mounted to a crank shaft mounted in the lateral walls and a nut is mounted to the crank shaft below the table board. An angle plate is mounted to the underside of the board, in contact with the nut. A rubber band is connected between the underside of the board and one end of the frame. Playing pieces resembling horses rest on top of the board. As the crank is rotated the corners of the nut act on the angle plate to cause the board to shake back and forth which has the effect of moving the horses along the board. Bumps can be provided on the board to make it more uncertain as to which of the horses will reach the other end of the board first.

Abstract: A method executed by a data processor for scanning a reverse range. The scan is conducted in an index for a table having an upper end and a lower end. The reverse range has a start key value for defining the reverse range, and the index has a set of keys representing a set of records and record attributes in the table. Each key in the set of keys has a RID designating a record in the table and a key value corresponding to an attribute of the record in the table. The method includes the steps of searching the index for a start key, selecting an upper bound of the reverse range, and, if the upper bound is the first key in the index, indicating that the index does not contain any key value within the reverse range, or, if the upper bound is not the first key in the index, then fetching each key below the upper bound in the index.

Abstract: A method of cutting a workpiece along a cutting path that is arcuate or that has one or more arcuate portions includes the step of determining a control parameter that is proportional to the angular velocity of the torch. The arc current supplied to the torch is regulated based on the control parameter and the linear advance rate of the torch, which in turn is a function of the material type and thickness of the workpiece. In one embodiment of the invention suitable for the cutting of holes, the control parameter is the diameter of the hole to be cut, which for a specified linear advance rate is inversely proportional to the angular velocity of the torch. The current is increased above a nominal current when the hole diameter is less than or equal to a predetermined limiting diameter, and otherwise is set at the nominal current. In other embodiments of the invention suitable for cutting holes or other shapes, the control parameter is the radius of curvature of the cutting path. Alternatively, the angular velocity can be used as the control parameter. Increasing the current at higher angular velocities and/or when cutting holes of small diameter tends to reduce the problem of the arc not following the desired cutting path and creating cut surfaces that do not conform to the desired cut surfaces.

Abstract: A walk behind self-propelled crawler snowplow includes a snowplow mechanism disposed on a front portion of a vehicle body, an engine disposed on a longitudinal central portion of the vehicle body for driving the snowplow mechanism, a left crawler belt and a right crawler belt disposed on a left side and a right side, respectively, of the vehicle body, and left and right electric motors disposed on a rear portion of the vehicle body for driving the left and right crawler belts, respectively. With this arrangement, the crawler snowplow has a good weight balance such that the load or weight of the vehicle body is born evenly by the crawler belts. Since the snowplow mechanism and the crawler belts are driven separately by different power sources, the crawler snowplow can exhibit a good traveling performance regardless of the load exerted on the snowplow mechanism.
