Abstract: A test wheel for a drivetrain test bench has a wheel rim, a wheel mounting, a blocking device, a wheel hub, and a wheel hub rotationally fixed on a wheel shaft. The wheel shaft and the wheel hub are held rotatably in the wheel rim by the wheel mounting, the blocking device is rotationally fixed to the wheel rim, and the wheel shaft can be rotationally fixed by a first connecting flange to a drive output shaft of a drivetrain to be tested. The wheel hub can be rotationally fixed by a second connecting flange to a drive input shaft and rotationally fixed to the blocking device by a third connecting flange so that rotation of the wheel shaft relative to the wheel rim is blocked. The third connecting flange can only be connected when the second connecting flange is not connected. A corresponding drivetrain test bench is disclosed.

Abstract: A record carrier has a servo track indicating an information track intended for recording information blocks. The servo track has a variation of a physical parameter, referred to as wobble. The wobble is modulated for encoding record carrier information, such as addresses. The servo track is subdivided in modulated parts in which the frequency and/or phase of the variation deviates from the wobble frequency, and non-modulated parts. The slope of the wobble is substantially continuous at transitions between the modulated and non-modulated parts by using wobbles starting at the maxima or minima of the wobble in a first part of the modulated parts.

Abstract: A data storage and replay device uses measurements of the evolution of performance of the storage medium (typically a flash memory circuit) to predict an error rate of retrieval from a region of the storage medium. The prediction is used as a basis for dynamically selecting an ECC for encoding the data prior to storage of the data. The ECC is selected from a plurality of available ECC's so that a fastest encodable ECC is selected that is predicted to produce no more than a predetermined post-decoding error rate given the information. On decoding the data, which is typically audio or video data, is decoded and replayed at a predetermined speed. In another embodiment, the data stored using a plurality of ECC's together and an ECC is selected dynamically for decoding, so that an output data rate can be maximized or power consumption on replay can be minimized.

Abstract: A hand held device for generating commands and transferring data between the hand-held device and a base device (including consumer electronic equipment). The hand-held device detects the motion of the device itself, interpreting the motion as a command, and executing or transferring the command. The motion of the device can include gestures made by the user while holding the device, such as the motion of throwing the hand-held device toward a base device. The commands generated by the user range from basic on/off commands to complex processes, such as the transfer of data. In one embodiment, the user can train the device to learn new motions associated with existing or new commands. The hand-held device analyzes the basic components of the motion to create a motion model such that the motion can be uniquely identified in the future.

Abstract: Light script command encoding for intelligent ambient lighting to enhance video content allows many controlled operating parameters to be specified simultaneously for a plurality of ambient light units. Initialization or setting codes specify luminance, chrominance, and light character, while separable change codes specify changes in the controlled operating parameters. The change code can comprise a functional description of the desired change, including a change type and/or a rate parameter. Using change codes, an ambient light source can fully execute the change through a range of values without further command encoding, reducing required bandwidth. Setting and change codes can be entropy coded and packetized to allow separate communication via two distinct data sources, and storage in subcode or metaspaces.

Abstract: A data processing circuit comprises an encoder circuit for encoding a data word, wherein each digit may have any one of three or more digit values. The data word is encoded so that digit counts in the data word satisfy predetermined criteria (the digit counts are counts of the numbers of the digits in the encoded data word that assume respective digit values). The encoder defines at least two digit maps, each digit map defining assignments of each of the available digit values to a respective different output digit value. The encoder selects at least two groups of digits within the input data word. Each group is associated with a respective one of the digit maps, the groups being selected so that when each digit map has been applied selectively to the digits from its associated group, digit counts of the number of times respective digit values occur in the data word will satisfy predetermined criteria.

Abstract: A record carrier (1) is described which has a servo track (4) indicating an information track (9) intended for recording information blocks, which servo track (4) has a variation of a physical parameter, a so called wobble. The wobble is modulated for encoding record carrier information, such as addresses. The servo track is subdivided in modulated parts in which the frequency and/or phase of the variation deviates from the wobble frequency, and non-modulated parts. The slope of the wobble is substantially continuous at transitions between the modulated and non-modulated parts by using wobbles (25,26,27,28) starting at the maxima or minima of the wobble in the first part of the modulated parts.

Abstract: Transmitters (116) for transmitting information and receivers (126) for receiving the information are defined by the information comprising a primary message and a secondary message combined in a same transmission or a same reception, which primary and secondary messages comprise communication protocol signaling messages, to avoid that a protocol conversion arrangement needs to be added to and to be placed between the transmitter (116) and the receiver (126). This increases the efficiency of the transmitter (116) and the receiver (126). The primary and secondary communication protocol messages are in accordance with first and second standards such as 802.11 a and later standards such as 802.11 n. The receiver (126) is able to detect the primary or secondary communication protocol message in case of the receiver (126) being in accordance with the first or second standard.

Abstract: A method of pre-processing gesture signals comprises the step of Filtering one or more signal segments by applying an infinite impulse response (IIR) filter both in a forward and in a backward temporal direction, so as to produce a band-limited gesture signal. The method may further comprise the step of matching the forward and backward initial conditions of the IIR filters to avoid any transients. Unevenly or sparsely sampled gesture signals may be subjected to the preliminary steps of interpolating the sampled signal, resampling the interpolated signal at a relatively high resampling frequency, filtering the resampled signal, and optionally downsampling the filtered signal, so as to produce a gesture signal having a well-defined sampling rate. An additional compression step may be carried out. The method may be utilized in conjunction with handwriting recognition methods.
