Abstract: A force feedback interface and method including an actuator in a non-primary axis or degree of freedom. The force feedback interface device is connected to a host computer that implements a host application program or graphical environment. The interface device includes a user manipulatable object, a sensor for detecting movement of the user object, and an actuator to apply output forces to the user object. The actuator outputs a linear force on the user object in non-primary linear axis or degree of freedom that is not used to control a graphical object or entity implemented by the host computer, and movement in the non-primary degree of freedom is preferably not sensed by sensors. The axis extends through the user object, and there are preferably no other actuators in the device, thus allowing the force feedback device to be very cost effective. Force sensations such as a jolt, vibration, a constant force, and a texture force can be output on the user object with the actuator.

Abstract: This invention relates to a process for controlling the orientation of secondary structures (A1, A2) with at least a crystalline part during the transfer of secondary structures from a primary structure (A) on which the secondary structures have an initial crystalline orientation identical to the orientation of the primary structure, onto at least one support structure (B), the process comprising: a) the formation of at least one orientation mark (Va, Va1, Va2) when the secondary structures are fixed to the primary structure (A), the mark having an arbitrary orientation with respect to the said initial crystalline orientation, but identical for each secondary structure, and b) when a set of secondary structures is transferred onto at least one support structure (B), an arrangement of the secondary structures so that their orientation marks can be oriented in a controlled manner.

Abstract: Enforcing a plurality of different policies on a stream of packets is disclosed. In lieu of running separate algorithms for each policy, the system exploits the commonalities of all of the policies. The conditions corresponding to the compiled rules are arranged in a condition tree and processed in a pipelined architecture that allows the results of the various stages to be carried forward into subsequent stages of processing. The rules for which all conditions have been satisfied can be identified by one stage of processing in one pass of condition tree traversal and are passed to subsequent stages. A rule table corresponding to an individual policy type can then be readily examined to determine partial or complete satisfaction of the rule of that policy type, without requiring a re-examination of the conditions underlying the rule. Additionally, corresponding actions can be taken where rule satisfaction is determined. This approach allows extremely high-speed policy enforcement performance.

Abstract: A force feedback mouse interface device connected to a host computer and providing realistic force feedback to a user. The mouse interface device includes a mouse object and a linkage coupled to the mouse that includes a plurality of members rotatably coupled to each other in a planar closed-loop linkage and including two members coupled to ground and rotatable about the same axis. Two actuators, preferably electromagnetic voice coils, provide forces in the two degrees of freedom of the planar workspace of the mouse object. Each of the actuators includes a moveable coil portion integrated with one of the members of the linkage and a magnet portion coupled to the ground surface through which the coil portion moves. The grounded magnet portions of the actuators can be coupled together such that a common flux path between the magnet portions is shared by both magnets.

Abstract: A mechanical interface for providing high bandwidth and low noise mechanical input and output for computer systems. A gimbal mechanism includes multiple members that are pivotably coupled to each other to provide two revolute degrees of freedom to a user manipulatable about a pivot point located remotely from the members at about an intersection of the axes of rotation of the members. A linear axis member, coupled to the user object, is coupled to at least one of the members, extends through the remote pivot point and is movable in the two rotary degrees of freedom and a third linear degree of freedom. Transducers associated with the provided degrees of freedom include sensors and actuators and provide an electromechanical interface between the object and a computer. Capstan band drive mechanisms transmit forces between the transducers and the object and include a capstan and flat bands, where the flat bands transmit motion and force between the capstan and interface members.

Abstract: Device for calibrating a pressure detector, particularly an infrasonic pressure detector. This device includes measurement means for applying to this detector a reference pressure which varies depending on time and all of whose spectrum components covering a predetermined frequency range are excited simultaneously with one and the same amplitude and a zero phase shift, or a constant delay, relative to each other.

Abstract: The present invention provides a solution in which a script containing general security parameters and access policies in a file is placed on an appropriate internal server. The location of the script may then be stored on an external server. When an end-user within the organization decides to purchase a wireless network device, he may attach it to his existing computer. The computer then may retrieve the security file location from the external server, retrieve the security file from the internal server using the security file location, and program the security file into the wireless device.

Abstract: Crescendo telephone ringers and methods of providing a crescendo telephone ring signal. The crescendo telephone ringer provides a gradual increase in audible ringing volume as a sequence of incoming electrical ring signals is detected. According to one embodiment, upon receipt of an incoming call, a first audible ring signal corresponding to a first detected electrical ring signal is set to a minimum volume. Subsequent audible ring signals corresponding to subsequent detected electrical ring signals are set to increasing volume levels, and finally to a maximum ringer volume.

Abstract: The invention is a method and apparatus for supplying both positive and negative gate drive power supply potentials to the top switch, in a typical half-bridge semiconductor power topology, from the bottom switch gate drive power supplies and without the use of transformer, capacitive or optical isolation. A known method of providing the positive top switch gate drive supply is enhanced and used in conjunction with a new and novel method for providing the negative top switch gate drive supply. The negative top switch gate drive supply is provided by an additional, lower power semiconductor switch, which is substantially synchronized with the bottom semiconductor switch, except for a slight turn-on delay. When this additional switch is gated “on” and conducting, the negative bottom switch gate drive power is connected to the negative top switch gate drive supply energy storage capacitors.

For one embodiment, low profile bus bars are used between the IMS PCB and a fiberglass PCB. The fiberglass PCB has a plurality of filter capacitors electrically connected across the bus structure. The geometry and layout of the bus bars provides a connection from the IMS PCB to the fiberglass PCB with very low parasitic inductance between surface mounted semiconductor power devices on the IMS PCB and filter capacitors on the fiberglass PCB.
