Abstract: A pet bootie is formed by a sleeve of pliable, disposable and liquid impervious material having a closed end for receiving an animal's paw and an open end. A loop of elastic material has an inner end secured to the sleeve at a predetermined distance from the open end of the sleeve and projecting outwardly from the sleeve. The loop is of predetermined extended length for allowing the loop to be extended around the sleeve and the animal's leg when the paw is inserted into the closed end of the sleeve, whereby the sleeve is secured in position.

Abstract: Drainage under a deck can be performed by a structure that includes hanging components and corrugated panels. For example, a hanging component can have connected first and second portions, with the first portion being connected to hang from one of the joists and extending downward to where it connects to the second portion, which is below the joist. The second portion can be connected to support of at least one of the panels from above. The upper surfaces of panels are sloped so that drainage occurs from a high part to a low part. The direction of slope and the direction of corrugations are not perpendicular, and can be approximately the same. The hanging components can, for example, be L-shaped brackets, U-shaped, or inverted T-shaped, and can be integrally formed by extrusion of plastic or can be metal. The panels can be corrugated plastic or metal sheets.

Abstract: Methods and devices which a surgeon may use to stabilize the beating heart during a surgical procedure on the heart. A stabilizing device may be introduced through an opening in the chest and brought into contact with the beating heart. By contacting the heart with the device and by exerting a stabilizing force on the device, the motion of the heart caused by the contraction of the heart muscles in a vicinity of a site of surgery to be performed, is effectively eliminated. A surgeon may contact the heart with the stabilizing means, assess the degree of movement of the anastomosis site, and exert a force on the stabilizing means such that the contraction of the beating heart causes only minimal excess motion at the surgery site. The stabilizing means may be attached to a rigid support or may be attached to a semi-rigid support which is rendered motionless mechanically, chemically, or by human intervention.

Abstract: The invention relates to an electric motor for electric fans having a casing with at least a lid with a hermetic seal and a method for assembly of the motor. The motor (1) has a casing (2) consisting of a cup-shaped part (5) and a lid (6) and an O-ring seal (7) inserted between them, the seal (7) comprising retaining means (8) so that it remains applied to one of the elements, either the lid (6) or the cup-shaped part (5). The method for assembly includes the steps of inserting an O-ring seal (7) in a seat (10) in the lid (6) or in the cup-shaped part (5), the O-ring seal (7) having retaining rings (11); and inserting each retaining ring (11) on a respective fixing pin (15) present in the lid (6) or in the cup-shaped part (5), so that the seal (7) remains positioned in the seat (10) applied to one of the elements, either the lid (6) or the cup-shaped part (5).

Abstract: An apparatus, includes a counter which counts a frequency of input of a first signal, a delay controller which generates a second signal by adding a delay to the first signal, the delay corresponding to the frequency, and a control circuit which halts the counter counting the frequency, when a phase difference between the first signal and the second signal is a predetermined value.

Abstract: A source node of a communication system selects one of a direct mode, a multi-hop mode, and a superposition mode as a transmission mode to be used for signal transmission from the source node to a destination node, taking into account data rates for a link between the source node and the destination node, a link between the source node and a delay node, and a link between the relay node and the destination node, thereby increasing the data rate, i.e., the throughput, of the entire communication system.

Abstract: A method of constructing a turbine blade for a gas turbine engine is provided. The method includes casting the blade, forming a plurality of spaced-apart notches in the airfoil proximate the tip on the pressure sidewall and forming at least one hole in each tip shelf communicating with the interior void of the airfoil for channeling cooling air from the interior void of the airfoil to thereby form a squealer tip.

Abstract: Layered structures such as photosensing arrays include layers in which charge carriers can be transported. For example, a carrier-transporting substructure that includes a solution processing artifact can transport charge carriers that flow to or from it through charge-flow surface parts that are on electrically conductive regions of a circuitry substructure; the circuitry substructure can also have channel surface parts that are on semiconductive channel regions, with a set of the channel regions operating as acceptable switches in an application. Or a first substructure's surface can have carrier-active surface parts on electrode regions and line surface parts on line regions; a second substructure can include a transport layer on carrier-active surface parts and, over it, an electrically conductive layer; to prevent leakage, an open region can be defined in the electrically conductive layer over the line surface part and/or an electrically insulating layer portion can cover the line surface part.
