摘要:
A scanner for demarcating each media sheet of a multiplicity of media sheets and a method thereof. The scanner includes a platen, a scanlid, an illuminating mechanism and a scanhead. The platen accommodates the multiplicity of media sheets. The scanlid is pivotally coupled to the platen and provides a background for scanning the multiplicity of media sheets. The illuminating mechanism is coupled to the scanlid and is activated for illuminating the background. The scanhead scans the multiplicity of media sheets. A single background image of the multiplicity of media sheets is captured by activating the illuminating mechanism during scanning. A single foreground image of the multiplicity of media sheets is captured by deactivating the illuminating mechanism during scanning. Edges of each media sheet are detected in the background image, and are combined with the foreground image to extract content thereof.

The present invention relates to improved methods for delivering bioadhesive, bioresorbable, anti-adhesion compositions. Antiadhesion compositions can be made of intermacromolecular complexes of carboxyl-containing polysaccharides, polyethers, polyacids, polyalkylene oxides, multivalent cations and/or polycations. The polymers are associated with each other, and are then used as fluids, gels or foams. By providing a product bag, the compositions can be delivered as gels or as sprays. By dissolving propellant gases in the compositions, the materials can be delivered as foams, which have decreased density, and therefore can adhere to surfaces that previously have been difficult to coat with antiadhesion gels. Delivery systems can also provide mechanisms for expelling more product, and for directing the flow of materials leaving the delivery system. Bioresorbable, bioadhesive, anti-adhesion, and/or hemostatic compositions are useful in surgery to prevent the formation and reformation of post-surgical adhesions. The biological and physical properties of such compositions can be varied as needed by carefully adjusting the pH and/or cation content of the polymer casting solutions, polyacid composition, the polyalkylene oxide composition, or by selecting the solids content of the composition. Antiadhesion compositions may also be used to lubricate tissues and/or medical instruments, and/or deliver drugs to the surgical site and release them locally.

In one embodiment, a single designated register in a codec is utilized by a controller to address and control a large number of expansion registers belonging to various expansion devices. The controller can write to or read from the designated register through an AC-link while complying with the AC '97 specification. The address and data bits in the designated register are used to write to or read from a target register in an expansion device. The designated register is selected from one of the 16 registers available to a design engineer in accordance with the AC '97 specification. An example of an expansion device that can be addressed and controlled through the designated register is an SSD device. In another embodiment, two designated registers in the codec register set are utilized. The controller can write address information into one of the designated registers while complying with the AC '97 specification. The controller can also write data to or read data from the other designated register through the AC-link while complying with the AC '97 specification. The address and data bits in the designated registers are used to write to or read from a target register in an expansion device. The two designated registers are selected from the 16 registers available to a design engineer in accordance with the AC '97 specification.
摘要:
An integrated heat pump and electrical heat control (12) has thermostat signal inputs (O, W1, W2, G, Y) along with a defrost sensor input (DF_IN). The defrost sensor (22) is located in an outdoor unit (4) which also includes a compressor contactor (CC), condenser fan (16) and reversing valve (18) relays (K4, K3, K2) controlled by micro-controller (U1). The normally closed condenser fan relay (K3) is energized through the defrost sensor forming a hardware lock-out in which the defrost sensor contacts must be closed for relay (K3) to be actuated de-energizing the condenser fan. The compressor contactor (CC) is energized through a low pressure switch (24) and high pressure switch (26) forming another hardware interlock. The evaporator fan is energized by relay (K1) controlled by micro-controller (U1) and matched to the compressor for improved efficiency and comfort.

摘要:
An electric control for gas furnaces which controls a two speed main blower fan and an induction draft fan based on inputs from a room thermostat, a high limit and an ignition control including a gas valve. The control has a circuit board having a power supply for providing 24 volts DC current source to drive DC relays and a 5 volt DC power source to power a microprocessor. 24 volt AC input signals are coupled to the input ports of the microprocessor through current limiting resistors and to AC ground through pull down resistors. AC ground is also connected to the IRQ port of the microprocessor. The output ports of the microprocessor are connected to a relay driver which in turn is connected to the relays. Several breakaway tabs in the board provide optional features such as eliminating a normally provided draft delay timing function. Test pads are provided on the board so that the board can be tested during manufacture. An optional feature is shown comprising an LED which can be used to indicate the status of the system. Another optional feature incorporates a zener diode and resistor coupled to each input port to increase input thresholds. This feature is provided for use with power stealing electronic thermostats.The control calibrates itself on a continuing periodic basis to read the AC inputs synchronously at the peak of their wave and switches the relays asynchronously based on the real time clock of the microprocessor.

An apparatus for lifting an aircraft may include a plurality of lifting mechanisms mounted on a supporting surface. Each lifting mechanism may be configured to impart an upward force on a component of the aircraft for lifting the aircraft off the supporting surface. The apparatus may include a beam structure configured to be mounted to the lifting mechanisms. The apparatus may also include a lifting beam suspended from the beam structure. A measurement device may be mounted to the lifting beam and may be configured to engage a jack point associated with the component to determine a weight of the aircraft when the aircraft is lifted off the supporting surface.
