    摘要： A system and method are provided for adaptively controlling timing in SAR ADC of a sampled analog signal within a conversion period. A state machine maintains a set of SAR states including a sampling state and a plurality of bit conversion states. A reference generator generates a quantization level reference for each of the bit conversion states within a parametric settling time thereof. A comparator compares the sampled analog signal with the quantization level reference over a parametric propagation time for determining a hit value for each hit conversion state. A clock generator adaptively defines signals for clocking the state machine and comparator for each SAR state, thereby adaptively delaying bit determination in each bit conversion state by an integration period not less than the settling time, while adaptively delaying quantization level reference generation for a next bit conversion state by a regeneration period not less than the propagation time.

    摘要： A photo card comprises a photographic image printed on a substantially durable card, such as a plastic card. An image is printed on at least a first side of the card, the image extending across a surface of the card, wherein substantially the entire area of the card is occupied by the image. In another example, the photo card includes multiple images on one or both sides of the card.

    摘要： A container with first and second opposing, parallel side panels; third and fourth opposing, parallel side panels which define an enclosure; optional first, second, third and fourth corner panels interposed between adjacent ones of the side panels; first and second top flaps respectively associated with the first and second side panels by first and second top creases or fold lines; and third and fourth top flaps respectively associated with the third and fourth side panels by third and fourth top creases or fold lines. The first top crease or fold line is coplanar with a top plane of the container; and the third and fourth top creases are offset below the top plane.

    摘要： The serial interface operable, for example, to facilitate high speed differential data transfer between integrated circuits provides level shifting of an incoming data signal using a switched capacitor technique which level shifts the common mode voltage with minimal attenuation and minimal reduction of bandwidths. The serial interface also includes a DC offset correction loop of the input data receiver path. The level shifting circuit operates by sensing the incoming common mode voltage of a differential data signal with a resistor divider and sampling the difference between the measured input common mode voltage and desired input differential voltages generated by a differential DAC in the DC offset correction loop on two small capacitors. The small capacitors are switched across larger in-signal-path capacitors cyclically, so that over time a charge will build up to give the desired level shift to shift the common mode voltage of the incoming signal to the level tolerable by low voltage high speed transistors in the receiving integrated circuit.

    摘要： An inflatable rescue collar is disclosed. The collar is formed of an elongated inflatable cylindrical tube having appropriate ends and which is of a size to extend around the upper torso of an individual. The bladder is generally toroidal in cross-section and defines an open channel along the length thereof through which a web strap extends. The strap is constructed such that it may be cinched adjacent the free ends thereof so as not to bind on an individual, or clipped so as to be capable of applying a compressive force about the upper torso of an individual.
