  • Patent number: 8341482
    Abstract: A user equipment comprises a transmitter and an adaptive modulation and coding controller. The transmitter is configured to transmit data over an air interface in a single transmission time interval with a first specified modulation and coding scheme, where the single transmission time interval has a plurality of transport block sets. In response to receiving a repeat request for retransmission of at least one particular transport block set, the transmitter retransmits the at least one of the particular transport block sets. The adaptive modulation and coding controller is configured to change the specified modulation and coding scheme to a second specified modulation and coding scheme, enabling a combining of a particular transport block set transmitted at the first specified modulation and coding scheme with a retransmitted version of the particular transport block set transmitted at the second specified modulation and coding scheme.

  • Patent number: 8340581
    Abstract: Methods and apparatuses for removing unwanted noise by a radio frequency identification (RFID) interrogator are provided. The interrogator transmits a transmitted signal while receiving a received signal. The received signal can include backscatter modulated signals from one or more RFID tags, as well as unmodulated reflections of the transmitted signal from the environment. The unmodulated reflections are undesirable and may make tag signal extraction difficult. A canceling signal is summed with the received signal to cancel or reduce the unmodulated reflections prior to tag signal extraction. In a specific embodiment, a phase shifted, amplitude adjusted reflection of the transmit signal is used by a directional coupler as the canceling signal.

  • Patent number: 8339942
    Abstract: According to one embodiment, in response to at least one of a link failure and node failure of a protected label switched path (LSP), network traffic is switched onto a protection path according to a fast re-reroute (FRR) scheme. A HELLO session is established with the remote node that is not immediately adjacent to the network element, including exchanging one or more HELLO messages with the remote node, each HELLO message having a time-to-live (TTL) value of greater than one if IP forwarding is used. The TTL value of the HELLO message is set to one if the HELLO message is sent via tunnel. In response to a request to restart, a resource reservation protocol (RSVP) traffic engineering (TE) graceful restart (GR) procedure is performed using information obtained from the one or more HELLO messages exchanged with the remote node during the HELLO session.

The system includes a coordinate creating module, a census transform module, a delay XOR calculation module, a stereo matching module, and a control module. Accordingly, by using the system extensible for performing stereo matching, depth information of corrected images can be acquired in real-time without using computer systems or software programs for special purposes. Furthermore, since the system extensible for performing stereo matching can be simply realized by hardware, the system and the method of the present invention can be easily applied to actual intellectual-type robots, industrial settings, etc.
