摘要:
A wind instrument with improved tonal characteristics by positioning an octave hole, an octave key mechanism, and/or a water key on a surface of the wind instrument that is not a tone-rich region. The wind instrument may be a woodwind instrument such as a saxophone or a brass instrument such as a trumpet. The octave hole may be placed on a concave portion of a curve in the wind instrument. The octave hole may be covered by an octave key mechanism that opens the octave hole using the same fingering that would open an octave key in a typical wind instrument. The water key may be placed on a portion of the body of the wind instrument that is not a tone-rich region of the wind instrument.

An electromagnetic impulse transmission system includes a plasma antenna generator, an electromagnetic impulse generator electrically coupled with the plasma antenna generator, and a ground plane structure operably associated with the plasma antenna generator. An electromagnetic impulse transmission system includes a plasma antenna, an electromagnetic impulse generator electrically coupled with the plasma antenna, and a ground plane operably associated with the plasma antenna. A method includes the steps of providing a plasma antenna generator, an electromagnetic impulse generator, and a ground plane structure; generating a plasma antenna with the plasma antenna generator; and transmitting an electromagnetic impulse from the electromagnetic impulse generator to the plasma antenna. The method further includes radiating the electromagnetic impulse from the plasma antenna such that at least a portion of the electromagnetic impulse is reflected by the ground plane structure.

A grain wagon includes a wheel supported frame supporting a container having inclined front and rear walls connected by opposite inclined side walls. Each side wall has inwardly projecting wall portions defining a wheel well for receiving longitudinally offset dual wheels or extra wide wheels. The rear wall includes a portion sloping between the wheel well wall portions to a forward grain removal zone, and generally triangular diverter walls extend from the rear wall to the wheel well wall portions. A corner discharge auger conveyor extends from the grain removal zone and has an upper portion which pivots to a stored position adjacent the front wall of the container. The dual wheels are positioned within the wheel wells by support members having end portions pivotally connected to the wagon frame and opposite end portions connected to the frame by laterally slidable clamping plates.

An eyeglass case for protectively housing eyeglasses. At least one wall of the case is formed with an inflatable chamber. The chamber may be selectively inflated. The eyeglass case, in its inflated state, protects the eyeglasses to a maximum degree and the case floats. The case may be inflated by blowing into a simple blowhole opening, with an integrated pneumatic pump, or with a gas cartridge that allows repeated inflation. The case may be formed with a soft inner pouch which is surrounded with an inflatable outer pouch, or it may be formed with a rigid bottom shell and a soft, inflatable top in the form of a lid.

A signalling system is used in conjunction with a mailbox, a newpaper tube or the like to signal the arrival of mail, a newpaper or the like. The system is highly visible in bright sunlight and is also visible at night and includes a ball that is held in an upper location adjacent to the mailbox and is released as soon as the door is opened to drop downwardly. Two serially connected switches couple a light bulb to a power source, with one of the switches being manually operated and the other switch being operated when the ball drops into its lower position.

An image forming apparatus is adapted to distinguish a presence between a full and a partially-full toner cassette. The image forming apparatus includes a load cell positioned in a developer station. The load cell is adapted to sense a mass of a toner cassette at least during an insertion of the toner cassette into the apparatus. A processor is adapted to determine a toner volume contained in the toner cassette based on a mass differential. A controller is adapted to drive or suspend a motor in the developer station to control an operation of the image forming apparatus. The controller controls the operation based on the toner volume.

An image forming apparatus comprises a controller that stores instructions, which cause the image forming apparatus to determine a characteristic measurement in response to a toner cartridge being partially inserted into the image forming apparatus. A pair of spaced apart sensors included on the image forming apparatus each contact an outer cross-sectional surface of a film on a delivery aperture of the toner cartridge. The image forming apparatus further includes an auger having at least one sensor for conducting a characteristic measurement on the film. The characteristic measurement corresponds to criteria programmed in the image forming apparatus for determining if the toner cartridge has a full toner level or a partially full (or low) toner level.

An integrated, multi-service network client for cellular mobile devices is described. The multi-service network client can be deployed as a single software package on cellular mobile network devices to provide integrated services including secure enterprise virtual private network (VPN) connectivity, acceleration, security management including monitored and enforced endpoint compliance, and collaboration services. The VPN network client is programmed to receive a web-based home page from an enterprise VPN appliance, process the web-based home page to identify a bookmark embedded within the response that corresponds to an enterprise webmail for the user and dynamically construct a user interface to have an input control native to the cellular mobile device for launching a native email client of the cellular mobile device to access the email without launching a web browser.
摘要:
A technique is provided for managing bundles of constructs that may individually fail. Each bundle has a repetitively updated resource amount for counterbalancing a transfer of a failure risk pertaining to the respective bundle. Construct data is stored and a value of the resource amount is calculated for an individual time instance based on the construct data. It is determined whether a construct of a first bundle has failed. If not, a value of a resource amount for the first bundle is calculated. If a construct has failed, a second bundle is generated that includes all constructs of the first bundle except for the construct having failed, and a value of a resource amount for the second bundle is calculated. The technique is particularly suitable for managing futures contracts that are based on a basket of credit default swaps as underlyings.
