Abstract: An indirectly heated cathode (IHC) ion source having improved life is disclosed. The IHC ion source comprises a chamber having a cathode and a repeller on opposite ends of the ion source. Biased electrodes are disposed on one or more sides of the ion source. The bias voltage applied to at least one of the cathode, the repeller and the electrodes, relative to the chamber, is varied over time. In certain embodiments, the voltage applied to the electrodes may begin at an initial positive voltage. Over time, this voltage may be reduced, while still maintaining the target ion beam current. Advantageously, the life of the cathode is improved using this technique.

Abstract: Techniques involve a motor assembly including a rotor and a stator. The stator includes a contact surface for contacting an outer surface of the rotor. The contact surface includes a rigid material. The motor assembly also includes at least one constraint disposed along a length of the motor assembly, where the constraint constrains a radial and/or tangential movement of the rotor relative to the stator. The at least one constraint may be disposed at one or more proximate ends of the motor assembly, and/or along the length of the motor assembly. The contact surface of the stator may have a profile including peaks and valleys, and in some embodiments, the contact surface may be treated to reduce friction and/or wear.

Abstract: The new embodiment of a highly efficient internal combustion hydraulic engine with a vane torquing device herein being provided, is designed to: a).—Maximize to the maximum extent possible the power and pressure produced by each combustion and convert it into mechanical use, and b).—To fit the engine snugly into all size trucks, pick-ups, heavy equipment, large and mid-size vehicles, snowmobiles, boats, buses, by placing the torquing device just below the cylinders. This new embodiment uses three electromagnetic actuators and one mechanical cam actuator to operate. It also has the following two additional features: first, an internal check valve located inside the block, which will make the engine more versatile, adaptable and supple to various road conditions. And second, a flexible longitudinal metal pin between the cam and the blind-type check-out-valve, to make the functioning of the engine more smooth and durable.

Abstract: A highly efficient two-stroke internal combustion engine with free pistons and a simple torquing vane device instead of a crankshaft is provided. Inside the motor, hydraulic oil is used to transmit power from the piston to the torquing vane device. The engine must have at least two cylinders. The cylinders have a special shape to allow the use of valves for a continuous production of torque and power. The use of solenoids and an electronic control unit coupled with a microprocessor are given to this invention a series of advantages that a regular engine available in the open market does not have. This engine produces high torque and is suitable for any duty use. The use of hydraulic oil will guaranty a smooth, fluent and quiet operation, lubricating and protecting all components inside the motor and a total distribution of temperature along all mechanisms thus a long life.

Abstract: An information handling system (IHS) has a server chassis assembly including a server chassis with a cold air inlet and a hot air exhaust and provisioned with compute components that are series aligned. A ducting structure positioned in the server chassis defines a cold air plenum in fluid communication with the cold air inlet and a hot air plenum in fluid communication with the hot air exhaust.

Air drops are provided longitudinally along the shroud corresponding respectively to the respective compute components being cooled. The air drops are each in fluid communication between the cold air plenum and the hot air plenum. Hot air from one compute component is routed directly to the hot air plenum away from other compute components.

The chassis includes a bottom segment having a base wall to receive the one or more compute components. One or more connecting cabling interconnects the compute components to assemble a fully functional IHS. A cover is fixedly engaged to the bottom segment to form a casing enclosing inserted IHS components.

The base panel has an upper chassis surface to receive selected compute components and infrastructure components that vary in height desired for the fully assembled IHS or rack in which the IHS will be inserted. The selected modular cover can have peripheral sides of a vertical height to complement a vertical height of the lateral guides of the base panel to create either a first height enclosure of a first height to house compute components of less than the first height or a second height enclosure of a second height to house compute components of less than the second height but greater than the first height. The latching structure is formed between the peripheral sides of the selected one of the first and second modular cover and the lateral guides of the base panel.

The IHS includes one or more connecting cabling interconnecting the at least two compute components.

Abstract: A chassis of an information handling system (IHS) includes a lateral segment that spans across a directional path of air travelling from an air intake side to an air exhaust side and including receiving affordances for insertion of a lateral support for a directional air mover. A user can select one of a first lateral support and a second lateral support that is insertable into the lateral segment and securable to the receiving affordances. The first lateral support has apertures of a first size to receive respective first fan modules and the second lateral support has apertures of a second size to receive respective second fan modules. An inserted one of the first and second lateral supports is selected based on a cooling air requirement corresponding to user selected compute components placed within the chassis to operate within the IHS.

Abstract: An apparatus that forms a source bushing, while comprehending the possible formation of electrically conductive films thereon, is disclosed. Such an apparatus may advantageously be used to isolate an ion source from other components within the ion implanter, as these components may be at different electrical potentials. In one embodiment, the source bushing is constructed from a material having a lower electrical resistance than is currently used. By constructing the bushing in this manner, the effects of the applied lower resistance films is reduced, as the change in effective resistance is reduced. In other embodiments, the source bushing is purposely lined with an electrically semiconducting material, so that the effects of the later applied lining are minimized. In either case, the electrical potential between the two devices that are being isolated by the bushing is more evenly applied across the bushing.

Abstract: A wireless communication system (100) employs a method and apparatus for activating a restrictive operating mode of a wireless communication device (101) in the event that the wireless device is lost or stolen. The wireless device has stored therein a password (205) associated with placing itself in a restrictive operating mode. Once placed in such a mode, the wireless device is only capable of contacting a restricted target device (107) as determined by either contact information (204) previously stored in the wireless device or the contents of a received message. After the wireless device is lost or stolen, a remote device (105) is used by the wireless device owner or a wireless service provider to send a message containing the password to the wireless device. Upon receiving the message, the wireless device checks for the password and, if present, automatically places itself in the restrictive operating mode.
