Title: An ear worn event radio with an antenna in a lanyard
Inventor: OPPERMAN NICHOLAS RICHARD JAME
IPC: H04B1/38
Filed: 2001-10-26
Abstract: A radio receiver (10), particularly for event radio, comprises a housing (12), a hooked element (30) extending from the housing for hanging the housing on a user's ear and rotatable for use on left or right ear, a radio receiver circuit contained in the housing and having an aerial input and a speaker output, and a speaker contained in the housing and connected to the speaker output of the receiver circuit for directing sound at the user's ear when the housing is worn on the user's ear. The receiver also has a lanyard (38) extending from the housing by which the user can hold the receiver and/or hang the receiver around their neck. The lanyard forms or contains an aerial (52,54) connected to the aerial input of the receiver circuit. Accordingly, the radio receiver can be hooked onto the ear, rather than needing to have any part inserted into the ear canal, which many people find uncomfortable or annoying. The housing may be of small size, but is provided with a lanyard to reduce the risk of the receiver being dropped or lost. Importantly, the lanyard provides the aerial for the receiver, enabling a reasonable antenna length to be provided without the necessity for aerial.

Title: Converting bits to vectors in a programmable logic device
Inventor: DANTE CONRAD
IPC: H03K19/177
Filed: 2003-06-18
Abstract: A circuit is disclosed for a programmable logic device (PLD) environment 10 that converts unordered bits in a PLD domain to fixed-width vectors in a vector domain. The fixed-width vectors may be used within a vector processing block (VPB) 24 that operates on data in vector format. The PLD includes multiple programmable logic blocks 20 that are configurable by a user. The logic blocks operate on data at a bit level resulting in unordered bits of information in a PLD domain. However, a vector processing block operates on data on a vector level (e.g., 8 bits, 16 bits, 32 bits, 64 bits, etc.). Thus, an interface 26 is coupled between the programmable logic blocks and the vector processing clock that converts at least a portion of the unordered bits of information from the PLD domain to one or more fixed-width vectors for use in the vector processing block. The interface may also perform scaling (Fig. 6) and/or sign extension (fig. 7) on the unordered bits, to further free up expensive resources in the PLD domain.

Title: Controlling uplink power level in a communication system terminal
Inventor: BREUER VOLKER
IPC: H04B7/005
Filed: 2004-06-16
Abstract: In soft handover, a mobile user entity 1 is in simultaneous communication with a number of cell base stations 2-4, e.g. via an uplink-dedicated physical channel 9, for normal use. Uplink power level is usually set by reducing power if any active cell requests power down. This is communicated by Transmit Power Control (TCP) signals on a downlink DPCH 5-7 from each cell. If the UE is also using high speed down link packet access (HSDPA), it will be communicating to only the serving cell C 2, e.g. via HS-DPCCH 8 and HS-DSCH 10. In the handover condition, cell A or cell B could be a better link than cell C and could be requesting power down. In the prior art this would also reduce the HSDPA uplink power level, resulting in the likelihood of acknowledgements of correctly received packets not being received by the cell C, leading to unnecessary resending of packets. The invention solves this problem by dividing the control, such that the control signals for the normal traffic sent from all the cells via DLPCH 5-7 control only the corresponding uplink power level on UL-DPCH 9 and separate control of the HSDPA on HSDCCCH is carried out according to signals received from cell C on DL-DPCH.
