An allergy testing system, for testing a patient for a plurality of allergies at substantially the same time, comprises a housing containing a plurality of packages or capsules containing an allergen and a needle, the needles being spaced apart from each other. The needles preferably carry the respective allergens on their tips. The housing is placed against the skin of a patient and an actuator is operated to engage the packages to move the needles to pierce or prick the skin of the patient, thereby applying the respective allergens to the pierced or pricked skin of the patient.

Some embodiments provide a method of specifying speed effects for playing a video clip. The method defines a set of speed effects for the video clip. It then displays in real-time a presentation of the video clip that accounts for the set of speed effects defined for the video clip. This method represents the playback speed of a video clip in terms of a graph that is part of a graphical user interface (“GUI”). This graph is defined along two axes, with one axis representing the playback time, and the other axis representing the content-time (i.e., the time within the video clip). A user can select and adjust the graph at different instances in time in order to change the playback speed of the video clip at these instances. Some embodiments use a deformable line bar superimposed on a rectangle that represents the video clip to represent playback speed.

A dip coating apparatus and method of dip coating. The apparatus includes a guide surface, a bendable tube, a carriage, and a support assembly. The bendable tube redirectionally engages the guide surface intermediate the first and second longitudinal ends of the tube. The carriage is vertically repositionable and cooperatively engages the tube proximate the first longitudinal end of the tube, whereby vertical repositioning of the carriage effects a change in the vertical distance between the first and second longitudinal ends of the tube. The support assembly releasably suspends an elongate workpiece for introduction of at least a portion of the workpiece into the tube through the first longitudinal end of the coating tube as the carriage is vertically repositioned upwards towards the support assembly.

The present invention is a small vehicle lamp comprised of: a generally cylindrically-shaped housing with an axial bore therethrough and forming a top opening and a bottom opening; a lens disposed on the top surface of the housing; a circuit board within the axial bore of the housing; at least one LED mounted on and electrically connected to the circuit board; a resistor disposed on the circuit board; a first cable wire and a second cable wire passing through the bottom opening of the housing and in electrical contact with the circuit board; and an potting compound disposed within the housing bore, in which the epoxy covers the resistor and circuit board and at least partially covers the LED and the cable wires. The lamp is configured such that it has a low profile and can be part of a system in which a plurality of the lamps are used on a vehicle.

A vehicle lamp assembly includes a housing having a top end, a body portion with an interior portion, and a lens portion covering the top end. The lamp assembly also includes an attachment member having a sleeve portion with an open top end and an open bottom end. The sleeve portion includes a catch member and is adapted to receive the body of the housing and to fit within an opening in a vehicle surface such that the lens portion of the housing is substantially flush with an outer face of the vehicle surface and the body portion of the housing is positioned substantially behind the surface. A securing device is positioned between a back face of the vehicle surface and the catch member of the attachment member, wherein the securing device prevents the attachment member and housing from being removed from the vehicle surface.

A surgical access device includes a single valve that forms a seal with a body wall and provides an access channel into a body cavity. The valve has properties for creating a zero seal in the absence of an instrument as well as an instrument seal for an instrument having a diameter up to about 37 mm. The valve can include a gel material and the access channel can include a protective sleeve to provide for wound protection during insertion and withdrawal of a sharp surgical instrument. The valve further comprises a cap ring which may be inserted or molded with the gel material. The protective sleeve may be bonded or molded around an inner diameter of the cap ring The protective sleeve may be a single tubular member, or may comprise a plurality of axially extending sleeve members having a plurality of axial slits The protective sleeve and the cap ring may comprise of the same or different materials The surgical access device further comprises at least one support ring disposed circumferentially of the valve forming a hollow space, and a wound retractor operatively placed in the hollow space. The wound retractor includes an inner ring, an outer ring, and a flexible sleeve connecting the inner ring and the outer ring.

An incrementally adjustable wound retractor, which provides access to a body cavity, includes an inner ring having a diameter greater than the desired diameter of the wound incision, an outer ring having an annular axis and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve disposed in a generally cylindrical form between the inner and outer rings. The outer ring includes first and second circular tubes spaced apart axially with each including a lumen having a rigid, noncompliant split hoop placed therein. The outer ring may be rolled over itself and around the annular axis to retract the sleeve with sufficient force to stretch the incision to the desired diameter. A gel cap seal may be coupled to the outer ring outside of the biological body to seal the opening produced by the wound retractor between the body cavity and outside the body cavity.
摘要:
A phase detector generates a first output signal if a feedback clock signal leads a reference clock signal by more than a first time. The phase detector generates a second output signal if the feedback clock signal lags the reference clock signal by more than a second time. If the feedback clock signal either leads the reference clock signal by less than the first time or lags the reference clock signal by less than the second time, neither output signal is generated. The phase detector may be used in a delay-lock loop in which the first and second output signals increase or decrease a delay of the reference clock signal by respective first and second delay increments. In such case, the each of the first and second delay increments should be less than the sum of the first and second times.
摘要:
A delay-locked loop (DLL) with feedback compensation is provided to increase the speed and accuracy of the DLL. After the variable delay line of the DLL is adjusted to minimize phase error, multiple clock cycles may be required before the adjusted signal is fed back to the phase detector. During this time, a signal replicating the adjusted signal is temporarily fed to the phase detector until the adjusted signal reaches the phase detector.
