Title: Stub out fluid quick connector with shut off valve interface
Inventor: PIERSON ERIK E
IPC: F16K51/00
Filed: 2005-08-03
Granted: 2011-10-11
Abstract: A fluid quick connector with a shut off valve interface is mountable on a first endform, such as a building plumbing stub out. The quick connector carries a retainer at an opposite end for releasable latching of a second fluid operative element to the stub out. An internally movable shut off valve is carried in the quick connector housing and is normally biased to a fluid blocking position. Insertion of a second endform through the second end of the quick connector housing overcomes the biasing force on the valve and moves the valve to an open fluid flow position allowing fluid flow between the stub out and the second endform.

Abstract: The present invention provides a removable shield attachment for hand-held digging tools which is mounted on the tool handle below the tool head so as to not interfere with gripping along the length of the handle. The shield generally comprises a mounting portion adapted to be mounted on the handle below the tool head, a shield portion extending laterally outwardly and upwardly from the mounting portion, and a slot positioned between the mounting portion and the shield portion adapted for passing a blade of the tool head therethrough. In use, the shield portion is positioned above the blade, thereby intercepting debris flying from the blade and towards the worker. The shield is particularly designed for digging tools having a slidably fit tool head that engages an outwardly tapered working end of the handle, with the shield being attached to the handle in the same manner as the tool head itself.

IPC: G06F21/62

Abstract: A digital content distribution system uses a Digital Rights Management (DRM) Controller that performs a set of arbitrary tests against the transfer request from one user to another such as user A to user B. Assuming these tests are successful, the DRM Controller sends an encryption key to transferring user A. This encryption key E is taken from a table of encryption key/hash pairs which have been provided to the DRM Controller by an external authority such as the content rights holder. User A encrypts the content using the key provided by the DRM Controller and then optionally calculates a hash over the encrypted form of the content E(X) and returns this value to the DRM Controller. On checking the returned hash against the hash from the table the DRM Controller knows that user A does indeed have the digital content X in good condition. The DRM Controller then instructs both users A and B that the transfer may proceed. The encrypted form of the content E(X) is transferred from A to B. Once the content transfer has completed B ensures that the received content has been physically written to non-volatile storage (to account for crashes etc. during the next step). B then calculates a hash over the received content and returns this value to the DRM Controller. If this value matches the value previously given then the transfer has been successful and the DRM Controller updates whatever central records are appropriate, while also returning a decrypt key to B to allow it to decrypt the content.

Abstract: La présente invention concerne un procédé de fabrication d'un article recouvert, ledit article pouvant être utilisé dans une fenêtre ou similaire et pouvant comporter au moins une couche réfléchissant l'infrarouge (IR) dans un revêtement à faible émissivité. La couche réfléchissant l'infrarouge peut être constituée d'argent. Dans certains modes de réalisation cités en exemple, on utilise au moins du krypton (Kr) gazeux dans la pulvérisation cathodique d'une couche réfléchissante à faible émissivité comprenant de l'argent. On a découvert que l'utilisation de krypton gazeux dans la pulvérisation de cibles d'argent produit une couche réfléchissant l'infrarouge présentant des propriétés améliorées de résistance et d'émittance.

Title: Semi-powered lower extremity exoskeleton
Inventor: ANGOLD RUSSDON
IPC: A61F2/74
Filed: 2006-04-13
Granted: 2014-07-08
Abstract: The lower extremity exoskeleton comprises two leg supports connectable to person's lower limbs and configured to rest on the ground during their stance phase. Each leg support comprises a thigh link and a shank link; a knee joint configured to allow flexion and extension between the shank link and the thigh link. The lower extremity exoskeleton further comprises an exoskeleton trunk connectable to the person's upper body. The exoskeleton trunk is connectable to the thigh links of the leg supports allowing for the flexion and extension between the leg supports and the exoskeleton trunk. Two torque generators are coupled to each of the knee joints. A power unit, capable of providing power, is coupled to the torque generators. In operation when a leg support is in a stance phase and climbing a slope or stairs, the power unit injects power into the respective torque generator thereby extending the respective knee angle.  When a leg support is in stance phase and not climbing a slope or stairs, the power unit does not inject any power to the respective torque generator, but without dissipating any stored power in said power unit, it forces the torque generator to resist flexion of the respective knee joint. When a leg support is in a swing phase, the power unit does not inject any power to the respective torque generator, but without dissipating any stored power in said power unit, it forces the torque generator to minimize its resistance to knee flexion and extension.

Abstract: The present invention is a device (10) for use in cleaning a fabric surface (16) of dust, dirt, pet hair and other debris (20) present on the surface (16). The device (10) includes a pair of cleaning members or rollers (60, 61) disposed on an underside of the device (10) which can roll with respect to the device (10) and with respect to one another. The rollers (60, 61) are selectively contacted with one another such that each roller (60, 61) can assist in removing debris (20) picked up by the opposite roller (60, 61) and dispensing the debris (20) into a collection chamber (32) releasably positioned within a housing (11). The removal of the debris (20) from each roller (60, 61) is also facilitated by opposed edges of a central opening (58) in the housing (11) that contact the rollers (60, 61) and direct the debris (20) into the debris collection chamber (32).

Title: High r-value window unit
Inventor: THEIOS JASON
IPC: E06B7/00

Granted: 2011-04-12
Abstract: In certain example embodiments of this invention, a window unit may include a vacuum IG (VIG) unit as an inboard lite and a monolithic lite (e.g., with an optional low-E coating thereon) as an outboard lite. A dead air space may separate the inboard and outboard lites.  A highly insulated frame may be used to support the inner and outer lites. The VIG  unit may be partially embedded or supported in the insulative frame, so that the insulating frame separates the VIG unit inboard lite from the outboard lite thereby reducing conductivity around the edges of the window unit so that R- value can be increased (and U-value decreased). In certain example embodiments, the total R-value of the window unit is at least about R-8, and more preferably at least about R-IO (compared to the much lower R-values of conventional IG  units).

Abstract: A needle may be fired into tissue by a needle firing mechanism, which may include a fork for holding the needle and a firing rod coupled with the fork. A spring urges the fork to a distal, fired position. A screw gear is coupled with the rod. A sled is positioned at the proximal end of the rod. A catch is configured to engage the sled when the sled is moved to a proximal position. The screw gear is operable to convert rotational motion from a motor and gear set into linear motion to move the rod proximally to engage the sled with the catch, thereby cocking the needle firing mechanism. The motor may also be used to translate the screw gear distally relative to the rod after the sled has engaged with the catch. A trigger is used to fire the cocked needle firing mechanism.
