摘要:
A bacon package has a stiffener sheet formed of plastic having an inner layer of foam polystyrene and solid films of polystyrene on opposite sides of the foam layer and coextruded therewith to form a web. The web of coextruded plastic is fed through an embossing station which forms an embossment defining the outer periphery of the stiffener sheet and, if desired, a plurality of annular embossments within the periphery. The embossed extrudate is then cut with heated knives around each embossment to seal the edges defined by the embossments. Apparatus other than heated knives may be used for sealing the edges.
摘要:
A rotor (38) for a gas turbine engine (10) has a low emissivity surface finish, or high emissivity surface finish (44), on at least a portion of its surface (42) to reduce temperature differentials between an upper portion and a lower portion of the rotor (38). This reduces bowing of the rotor (38) to allow the gas turbine engine (10) to be started without harmful vibrations of the rotor (38).

A control arrangement (10) comprises a first selectable controller (12) for controlling an action, and a second selectable controller (14) for controlling the action. The arrangement also includes a selector (22) for selecting one of the controllers (12, 14) to control the action. The arrangement (10) further includes a first heat exchanger (16) associated with the first controller (12) to effect a transfer of heat between the first controller (12) and the first heat exchanger (16). The arrangement also includes a second heat exchanger (18) associated with the second controller (14) to effect a transfer of heat between the second controller (14) and the second heat exchanger (18).
摘要:
A method and arrangement (100) for PRACH burst channel detection in a UTRA TDD wireless communication system in which training sequences are constructed from a single periodic base code. Unwanted cross-correlation peaks, having magnitude less than correlation peaks, are removed (440) from the correlator outputs, maintaining optimal signal-to-noise ratio of the channel estimates, providing a low probability of false detection, and extending the cell size of a CDMA network to that determined by the guard period duration. The cell size can be extended further by ensuring that no transmissions are scheduled for the timeslot subsequent to that in which the channel estimation bursts are scheduled.
摘要:
A method, NodeB (320) and User Equipment (330) for TDD operation in a communication system operating in TDD mode in a frequency band allocated for FDD operation. Preferably, operation is in TDD uplink and downlink mode in a first frequency band designated or normally used for FDD uplink communication, and in TDD downlink-only mode in a second frequency band designated or normally used for FDD downlink communication. The invention provides the following advantages: Provides a flexible method to deploy a time division duplex architecture in frequency division duplex spectrum. Allows flexible use of system capacity by adjusting the uplink and downlink capacity split. Removes previous FDD duplex restrictions.
摘要:
A cellular communication system comprises a Multiple-In Multiple-Out, MIMO, transmitter (101) and receiver (103). The MIMO transmitter (101) comprises a message generator (303) for generating MIMO messages comprising selected training sequences and transceivers (305, 307, 309) transmitting the messages on a plurality of antennas (311, 313, 315). The training sequences are selected by a midamble selector (317) from a set of training sequences in response to an associated antenna on which the message is to be transmitted. The set of training sequences is associated with the cell of the MIMO transmitter and comprises disjoint subsets of training sequences for each of the plurality of antennas. The receiver (103) comprises a transmit antenna detector (419) which determines which antenna of the MIMO transmitter the message is transmitted from in response to the training sequence of the received message.
摘要:
An efficient scheme for CDMA coding constructs codes by generating longer code sequences (430) via concatenation, from an existing set of short sequences (410, 420). The sequences may be spreading, scrambling and or training or channel estimation (such as midamble) sequences. The invention allows extension of sequences without performing an exhaustive search for sequences with optimal desired properties, as well as extension of the sequence duration to improve the detection of wanted signals via the use of a conventional matched filter, a multi-user detector or an adaptive filter/equaliser.
摘要:
A method, system and computer program product for creating a preload. A preload may be stored onto a computer system prior to the computer system being manufactured. One or more attributes of an object of a preload may be defined. Each preload object may be an aggregation of one or more software element objects. A comparison may be made between the attributes in each software element object with the one or more attributes in the defined preload object. Upon identifying one or more software element objects whose attributes comprise the one or more attributes of the defined preload object, one or more part numbers associated with the one or more identified software element objects may be transmitted to a manufacturing system. Software associated with the identified one or more software element objects may be retrieved and installed onto a preload associated with the defined preload object.
