Title: Central vacuum with acoustical damping
Inventor: RITTMUELLER STEPHEN P
IPC: F01N13/00
Filed: 1996-11-22
Granted: 2003-10-14
Abstract: A central vacuum unit having an acoustic damping system is provided.  The central vacuum unit includes a canister having a sidewall forming a hollow interior and a lid closing an end of the sidewall, a vacuum motor within the canister which emits noise during operation, at least one cooling air inlet for admitting cooling air into the hollow interior, and at least one cooling air outlet in the sidewall for exhausting the cooling air from-the hollow interior.  Additionally, the sidewall has an exhaust port and the motor has an exhaust pipe extending through the exhaust port.  The acoustic damping system includes an acoustic damping tunnel, an acoustic damping canopy, and an exhaust port seal.  The acoustic damping tunnel is within the hollow interior and forms a pathway between the hollow interior and the cooling air outlet.  The pathway is lined with a sound absorbing material so that the tunnel reduces noise emitted from the hollow interior through the cooling outlet.  The acoustic damping canopy is attached to the canopy over the cooling air inlet.  The canopy has an inlet and forms a serpentine pathway between the canister cooling air inlet and said canopy inlet to reduce noise emitted from the hollow interior through the canister cooling air inlet.  The exhaust port seal covers the exhaust port to reduce noise emitted from the hollow interior through the exhaust port.  The exhaust port seal preferably includes flexible foam bonded to the canister sidewall.

Title: Three pole forced permanent magnet rotor with dc twister
Inventor: KIM NUNG-SOO P
IPC: H02K53/00
Filed: 1997-01-30
Granted: 2001-07-03
Abstract: This device has a three-pole forced permanent magnet rotary wheel which can be actuated with a small electrical input to produce a powerful high torque. A plurality of permanent magnets referred to as wheel magnets, are mounted in a circular ring manner on the surface of a rotary wheel and they are located equidistant from one another and radially from the center of the rotary wheel. The total number of wheel magnets may be any even number equal to or greater than four depending on the space allowed on the rotary wheel. The polarities of the wheel magnets are alternately positioned juxtaposed to station magnets located adjacent to the rotary wheel. Each station magnet is mounted on a shaft which is, in turn, mounted on a main frame, and the shaft is rotatable by a DC twister. The total number of station magnets is an odd number, which is less than the total even number of the wheel magnets. The station magnets are equidistant from each other and are perpendicular to the respective neighboring wheel magnets. The polarities of the station magnets face towards the right and left sides, in front of the single pole of the neighboring wheel magnets. Each time a DC twister is activated to rotate its associated station magnet through 180 degrees or close to 180 degrees, the repelling and attracting magnetic forces between this station magnet and its neighboring wheel magnet causes the rotary wheel to rotate. A plurality of electrical conducting switches for activating all the twisters are located at specific points on the rotary wheel so that the station magnets are rotated sequentially for producing a continuous rotation of the rotary wheel.

Granted: 2008-12-30
Abstract: This invention relates to the use of topically applied thyroid hormones and thyroid hormone-like compounds which are receptor binding ligands, either agonists or antagonists, to improve the appearance of the skin and underlying subcutaneous fat and improve certain medical conditions when applied topically. These compounds can be used to treat skin conditions such as stria, cellulite, roughened skin, actinic skin damage, intrinsically aged skin, photodamaged skin, lichen planus, ichthyosis, acne, psoriasis, wrinkled skin, and to diminish the size and improve the appearance of skin scarring from surgical or naturally occurring wounds, and to reduce the incidence of hyperkeratotic scarring. These hormones or hormone analogs will also increase the rate of epithelialization and collagen production. The thyroid agonists and antagonists may also promote differentiation and amelioration of dedifferentiated skin in premalignant lesions. The thyroid agonists and antagonists can be active in all organisms which contain the thyroid hormone receptors, notably amphibians, birds and subjects. Combination with Vitamin D analogs glucocorticoid and retinoids will potentiateand modify the effects of the thyroid hormones for increased benefit.  Side effects of thyroid hormones which occur when the hormone is given orally and prevent usefulness for the above conditions are prevented when the hormone is topically applied.

Title: Asynchronous data pipe for automatically managing asynchronous data transfers between an application and a bus structure
Inventor: SMYERS SCOTT D
IPC: G06F13/12
Filed: 1997-02-19
Granted: 2008-11-04
Abstract: An asynchronous data pipe (ADP) automatically generates transactions necessary to complete asynchronous data transfer operations for an application over a bus structure. The ADP includes a register file which is programmed and initiated by the application. The register file includes the bus speed, transaction label, transaction code, destination node identifier, destination offset address, length of each data packet, packet counter, packet counter bump field, control field, and a status field. During a data transfer operation, the ADP generates the transactions necessary to complete the operation over the appropriate range of addresses, using the information in the register file as a template. The ADP increments the value in the destination offset address field for each transaction according to the length of each data packet, unless the incrementing feature has been disabled and the transactions are to take place at a fixed address. The packet counter represents the number of transactions remaining to be generated. The packet counter value is decremented after each packet of data is transferred. The application can increment the packet counter value by writing to the packet counter bump field. A multiplexer is included within a system having multiple ADPs for multiplexingthe informatio n from the ADPs onto the bus structure. A demultiplexer is included within a system having multiple ADPs for routing information fro m the bus structure to the appropriate ADP.
