The device includes an imager picking up an image of a finger vein pattern, a light source emitting light adapted to be transmitted through the finger, an image operating unit matches the image, guides indicating the position of picking up the finger image, a detector detecting the contact between the finger and the guides, another light source radiating light reflected from the thick of the finger, a switch which is depressed by the forward end of the finger, a further light source emitting light transmitted through the forward end of the finger, and a light-sensor receiving the light from the further light source through the finger.

The present invention generally provides improved medical devices, systems, and methods. Embodiments may be particularly well suited for the treatment of dermatological and/or cosmetic defects, and alternative embodiments may be configured for treatment of a wide range of target tissues. Some embodiments of the present invention apply cooling with at least one small, tissue-penetrating probe, the probe often comprising a needle having a size suitable for inserting through an exposed surface of the skin of a patient without leaving a visible scar. The cooling may remodel one or more target tissue so as to effect a desired change in a composition of the target tissue and/or a change in its behavior. Exemplary embodiments make use of replaceable needle probes supported by a probe body handle, with small needle probes often being replaced during treatment of a single patient. Unlike the large format cryogenic cooling systems of the past, small cryogenic cooling needle probes may dull or be damaged by insertion. Careful control over the control of cryogenic cooling fluid into a needle probe can allow the length of the active cooling to be controlled through depletion of liquid from an evaporating cryogenic cooling flow. Hence, even needles having similar external structures may provide differing lengths of an iceball along the needle axis. Surprisingly, small cryogenic cooling needles and/or other cryogenic cooling probes having a lubricious coating will allow safe removal of the probe from the treatment region while at a least a portion of the tissue remains frozen, significantly decreasing the overall time for a procedure involving many insertion/freeze/removal cycles.

The present invention is directed to a data cartridge library system that realizes a reduced cost by reducing the number of certain components, especially expensive components, that are needed to perform certain functions within the library. With respect to certain functions, a reduced cost is realized by using lower precision componentry in combination with componentry that compensates for lower precision while still providing a reduced component cost with respect to a given function. In one embodiment of the invention, a data cartridge picker is provided that: (1) uses a single electro-mechanical device for the functions of grasping a data cartridge, retracting a grasped cartridge from a drive/storage location, inserting a grasped cartridge into a drive/storage location, and releasing a grasped cartridge once position in a desired location; (2) is capable of compensating for variations in cartridge positioning; (3) has a gripping mechanism that moves in a sinusiodal manner; and (4) avoids the wear and tear associated with moving fully retracted gripper mechanism that is not holding a data cartridge from a fully retracted position to a position at which a cartridge can be retrieved. Another embodiment provides a elevator mechanism for moving the cartridge picker in which the guiding portion of the mechanism is also part of the portion of the mechanism that moves the cartridge picker. A further embodiment employs a face plate extension that facilitates insertion of a data cartridge into a drive by a low precision cartridge transport device. Yet another embodiment provides a removable data cartridge holder that: (1) includes a box-like structure for holding data cartridges and a dust cover that can be placed over the opening of the box-like structure when the holder is not in use and when the holder is in use, attached to the box-like portion; (2) an orientation structure that prevents insertion of a data cartridge into the box-like holder if the cartridge is improperly oriented; and (3) retention clips for preventing accidental dislodgement of a data cartridge located in the box-like structure.

An improved drink can is disclosed wherein the drink can has a drink opening and a vent opening which are positioned opposite from each other with respect to a central portion of a top end of a drink can. The tab is attached to the central portion and can be pulled upward to open the drink opening then pushed back downward to open the vent opening. To aid in opening the vent opening with the tab, the vent opening may have a ridge to provide additional leverage when the tab pushes downward on a score line that defines the vent opening. The tab may be enlarged so that upon breakage of the score line to the vent opening, the tab contacts the top end of the can and does not allow the user's finger to proceed into the vent opening and possibly cut the user's finger.

A device for cleaning the ear canal of cerumen or contaminants includes a handle, a material expandable upon exposure to a fluid, and a limiter connected to the handle operative to prevent insertion of the expandable material into the ear to a depth which could contact the ear drum. Fluid is passed through the handle and through apertures to the ear canal, and or to the expandable material, whereby the ear canal and expandable material are moistened. The expandable material expands to contact the ear canal walls and cerumen, whereby the cerumen may be extracted by withdrawing the handle and connected expandable material from the ear. The fluid may be an alcohol solution, which loosens cerumen, reduces the potential for infection, and promotes drying of the ear canal.

An integrated grip and rail system is provided. Included is a firearm and the firearm grip. The grip is configured to be disposed in front of the magazine well and provide a stable grip point which does not allow a user's thumb or other appendage to be disposed between the grip and magazine well. The grip is configured so as to not interfere with the pivoting relationship between the weapon upper and weapon lower during partial or complete disassembly of the weapon. The rear region may also have a portion extending rearward along at least part of each side of the magazine well to form feed ramps as a part of the magazine well extension. Included is a magazine well extension mechanically coupled to a forearm rail system for mounting to the firearm.

An ESD protection device including a transistor structure with resistive regions located within active areas thereof. The transistor structure is formed of one or more MOS transistors, preferably N-type MOS transistors. The drain regions of the transistors are modified to reduce the conductivity of those resistive regions by preventing high carrier concentration implants in one or more sections of the drain regions. This is achieved by modifying an N LDD mask and the steps related thereto, as well as a silicide exclusion mask and the steps related thereto. The modifications result in the omission of N LDD dopant from the area immediately adjacent to the underlying channel. In addition, portions of a spacer oxide remain over the drain region to be formed. Subsequent implant and siliciding steps are effectively blocked by the spacer oxide that remains, leaving a low-density drain (LDD) charge carrier concentration in those regions, except where omitted. The resistivity of those resistive LDD regions is greater than the resistivity of the adjacent portions of the drain region. The result is more uniform turn-on of ESD transistor fingers in a protection device set without the need to add valuable layout space and without increased processing steps.

A button head tie has a button head and a tie strap. The button head is a generally flat member having an aperture for receiving the tie strap. The aperture includes lead-in ramps to facilitate tie strap insertion and is configured to prevent angled tie strap insertion. The tie strap is a flat elongate member having a wedge that is captured within the aperture. The remainder of the strap passes through the aperture. The wedge and strap have teeth and serrations on both sides, respectively, the teeth and serrations being engageable. In use, the strap is looped around a bundle and inserted into the aperture to either side of the wedge. Strap insertion force is reduced by standoff tabs which elevate the wedge out of aperture, temporarily, during installation. When loop tension is applied to the bundle, the wedge is pulled into the aperture, compressively locking the strap.
