Abstract:
A framework is provided for reducing the number of locations modified when hiding data, such as a digital watermark, in binary data. The framework complements data hiding techniques, such as digital watermarking techniques. After determining potential embedding locations according to an underlying technique, a data structure is created with values associated with those locations. A parity calculation is performed on the values in the data structure. The calculated parity is compared with hidden data to determine locations for modifications. Manipulations are then performed to reduce the total number of modifications needed to represent the hidden data. Modifications are made to the binary data according to the underlying technique. During decoding of the hidden data, the same locations can be determined, the same data structure can be created with the modified values, and a parity calculation is then performed to decode the hidden data.
Abstract:
An infant carrier apparatus comprises a support frame having opposite first and second sides, a handle pivotally coupled with the support frame, and a stop mechanism. The handle is operable to rotate relative to the support frame between a first position inclined toward the first side, and a second position inclined toward the second side. The stop mechanism is adapted to arrest the handle at an intermediate position when the handle is rotated from the first position toward the second position, wherein the intermediate position is located between the first and second position. In addition, other embodiments also described a method of adjusting the infant carrier apparatus.
Abstract:
A direct current cable termination apparatus for terminating a high voltage direct current cable, the apparatus includes a current-carrying device including a terminal portion of the direct current cable, the cable at least including an electrical conductor, a electrically insulating layer located outside of the electrical conductor, and a conductive shield located outside of the insulating layer and the electrical conductor. The apparatus includes a housing including a tubular outer shell with an inner periphery, the outer shell defining a longitudinal axis and being formed by an electrically insulating and polymer-containing material. The current-carrying device extends in the axial direction of the outer shell. Along at least a part of the axial extension of the current-carrying device the outer shell extends axially with a space between its inner periphery and the current-carrying device. The housing is adapted to separate the space from an atmosphere outside the outer shell.
Abstract:
For selecting suitable bonding parameters for forming wire bonds onto bond pads of a substrate, one or more indentations are made onto at least one bond pad of the substrate with an indentation tool by applying a series of predetermined forces onto the at least one bond pad with the indentation tool. A depth-force profile of the substrate is measured comprising a relationship between each predetermined force that is applied and a resultant depth of the indentation made by the indentation tool. An appropriate set of bonding parameters suitable for forming wire bonds on the substrate is determined based on the measured depth-force profile.
Abstract:
An electronic device paired with an infrared remote control, includes a display screen having a display area, at least one infrared emitter, at least one infrared receiver, a prism and a processing unit. A prism is adjacent to the at least one infrared receiver for converging the infrared rays from the at least one infrared emitter and the infrared remote control to the at least one IR receiver. A processing unit is for activating and then deactivating the infrared emitters one after another, identifying operations of a user on the display area by analyzing the interception of the infrared rays emitted from each of the infrared emitters, identifying operations of a user according to the infrared signals from the infrared remote control and executing corresponding functions associated with the operations of the user.
Abstract:
A display device includes a display portion, a cantilever, a rotating disc unit, a base, and two cables. The cantilever has an upper end connected with the display portion, allowing the display portion to rotate relative to the cantilever about a first axis. The rotating disc unit is connected with a bottom of the cantilever, allowing the cantilever to pivot relative to the rotating disc unit about a second axis, which is parallel with the first axis. The base is connected to the rotating disc unit in a manner allowing the same to rotate relative to the base about a third axis, which is vertical to the first and second axes. The cables extend downward from the display portion along the cantilever and are inserted into the rotating disc unit. The cables enter the base after being placed adjacent to one another within the rotating disc unit.

Abstract:
An apparatus for de-aering, oxygenating and controlling a temperature of blood in an extracorporeal blood circuit. The apparatus includes a housing, a manifold body, a heat exchanger, and an oxygenator. A blood inlet tangentially directs blood into a first chamber of the housing. The manifold body is disposed in a second chamber, and includes a core and a plurality of vanes that define channels. The heat exchanger is arranged around the manifold body, and the oxygenator around the heat exchanger. The channels are open to the heat exchanger. An established blood flow path includes rotational flow within the first chamber to separate air from the blood, generally longitudinal flow from the first chamber and along the channels, and generally radial flow through the heat exchanger and the oxygenator. With this construction, gross air removal occurs prior to the blood passing through the heat exchanger and oxygenator.
