  • Publication number: 20150047203
    Abstract: A stationary blade (10) for a blade set (4) of an electrically operated hair cutting appliance (1), including a first wall (20) and a second wall (30), each wall defining a first surface (22a, 32a), a second surface (22b, 32b) facing away from the first surface, and a laterally extending leading edge (23, 33) defining a plurality of laterally spaced apart longitudinally extending projections (24, 34), wherein the first surfaces of the first and second walls face each other, at least at their leading edges (23, 33), while facing projections along the leading edges of the first and second walls are mutually connected at their tips (26, 36) to define a plurality of generally U-shaped teeth (12), and the first surfaces of the first and second walls define a laterally extending guide slot (16) for a movable blade (40) of said blade set between them.

  • Patent number: 7933207
    Abstract: Consistent with an example embodiment, there is a signal processing circuit. Linking multiplexing (L-MUX) circuits, link respective pairs of stream processing circuits. Each L-MUX circuit is individually switchable to a normal mode and a replacement mode; in normal mode, it passes a first stream of samples values between the stream processing circuits in the respective pair of the L-MUX circuits; in replacement mode, it supplies successive sample values from a second stream from the communication structure to a receiving one of the stream processing circuits in the respective pair. A control circuit keeps a selectable one of the multiplexing circuits in the replacement mode so the selectable one of the L-MUX circuits passes a stream of successive samples from the second stream to the receiving one of the processing circuits in the respective pair of L-MUX circuits, while keeping at least part of the other L-MUX circuits in the normal mode.

  • Publication number: 20090306800
    Abstract: A receiver circuit has a chain of stream processing circuits (10a-c)—having control parameter inputs for receiving control parameter values. To facilitate design of circuits that receive data with a variable block size, an included control circuit (14) selects block sizes of blocks of samples in the respective streams of a plurality of the stream processing circuits (10a-c), a control parameter value for each particular block. The control circuit transmits instructions specifying the selected block sizes and control parameter values to local control circuits (11). Each local control circuit is coupled to the control circuit (14) and the control input of a respective corresponding stream processing circuit (10a-c). Each local control circuit (11) receives at least part of the instructions and applies parameter values from the instructions to its corresponding stream processing circuit (10a-c). The local control circuit (11) controls timing of control parameter updates using block sizes from the instructions.

  • Publication number: 20080155491
    Abstract: An electronic circuit, in particular a receiver circuit contains a chain of stream processing circuits (I0a-c). The stream processing circuits (IOa-c) have control parameter inputs for receiving control parameter values. In order to facilitate design of circuits that receive data with a variable block size, a control circuit (14) is included that selects block sizes of blocks of samples in the respective streams of a plurality of the stream processing circuits (10a-c), a control parameter value for each particular block. The control circuit transmits instructions that specify the selected block sizes and control parameter values to local control circuits (11).
