  • Patent number: 7561034
    Abstract: A load warning system for use with a vehicle having a load-support portion, a frame, and a vehicle-support portion movably coupled to the frame. The system has an engagement portion mountable to the vehicle-support portion or the frame and is movable therewith as a unit. A load indicator is mountable to the other one of the vehicle-support portion or the frame, and is spaced apart from the engagement portion when in a first position. The load indicator moves to a second position and engages the engagement portion when the frame moves a selected distance in response to the load applied to the load-support portion. The load indicator provides a signal upon being moved to the second position. A warning indicator is coupled to the load indicator and provides an improper load warning to a user in response to the signal from the load indicator.

  • Publication number: 20090068066
    Abstract: A liquid dispensing device. The liquid dispensing device has a tray for holding a liquid at a relatively constant level. A syringe is used for drawing fluid from the tray. A liquid container containing a liquid is positioned upside-down in the tray. Atmospheric pressure on the liquid in the tray and a vacuum inside the liquid container prevents liquid from draining from the container except when the liquid level in the tray drops to a level sufficient to allow air into the liquid container and to allow fluid to flow from the liquid container into the tray. The fluid flows from the liquid container into the tray until the level of liquid in the tray returns to the relatively constant level. The positioning of the syringe for drawing fluid is simplified in that the level of fluid in the tray is maintained at an approximately constant level despite withdrawal of quantities of fluid from the tray.

  • Publication number: 20080146092
    Abstract: A technique is disclosed which uses captive fasteners to create secure electrical connections between a printed circuit board (PCB) and an external conductor. The captive fastener provides both a mechanical attachment for an electrical lead and an electrical connection to a circuit on the PCB. The captive fastener may be a captive nut, a captive stud, a standoff, a clip, or another suitable type of captive fastener. The captive fastener may be made of electrically conductive material and it may be in electrical contact with a circuit on the PCB.

  • Patent number: 7364702
    Abstract: A liquid dispensing device. The liquid dispensing device has a tray for holding a liquid at a relatively constant level. A syringe is used for drawing fluid from the tray. A liquid container containing a liquid is positioned upside-down in the tray such that the opening of the liquid container defines a vertical position that is slightly below the liquid level in the tray. Atmospheric pressure on the liquid in the tray and a vacuum inside the liquid container prevents liquid from draining from the container until the fluid level in the tray drops to a level approximately equal to the vertical position of the opening. The positioning of the syringe for drawing fluid is simplified by reason of the fact that the level of fluid in the tray is maintained at an approximately constant level despite withdrawal of quantities of fluid from the tray.

  • Publication number: 20070151096
    Abstract: A monolithic, multi-layer heating element (26, 126, 226) forms the high temperature tip (22, 122, 222) of a glow plug assembly (20). The heating element (26, 126, 226) includes a conductive core (48, 148, 248) which is surrounded by an insulator layer (50, 150, 250), which in turn supports a resistive layer (52, 152, 252). An optional conductive jacket (172) can surround the resistive layer (152). These layered components are pre-formed in prior operations and then assembled one into the other to form a precursor structure. The precursor structure is transferred to a die (54, 64, 164), where it is compressed to form a so-called green part having dimensional attributes proportional to the finished heating element (26, 126, 256). The individual layers remain substantially intact, with some boundary layer mixing possible to enhance material-to-material bonding. The green part is sintered to bond to various materials together into an essentially solid mass.

  • Publication number: 20060276552
    Abstract: A method for cerebral and systemic cooling by providing a nebulized liquid having a boiling point of 38-300° C. The nebulized liquid is delivered as a mist or a spray via the nasal and/or oral cavities of a patient. The mist causes cooling by direct heat transfer through the nasopharynx and hematogenous cooling through the carotids and the Circle of Willis. Compositions and medical devices for cerebral and systemic cooling are also provided. Cooling assemblies, and methods of use, are also provided that include flexible balloon assemblies that are inserted to various locations in a patient's body. The flexible balloons are then infused with a liquid having a temperature between about ?20° C. and about 37° C. The flexible balloon assemblies can be inserted into the nasal cavity, oral cavity, throat, stomach, and other locations to effect cerebral cooling.

  • Publication number: 20060118573
    Abstract: A small item dispense module. Small items are stored inside a first chamber. The small items are then transferred to a second chamber having a first singulator. The first singulator transfers the small items to a third chamber having a second singulator. The second singulator transfers the small items from the third chamber to a discharge tube having a discharge gate. The discharge gate allows for the dispensing of the small items so that they easily accessible. Preferably, the dispense module further includes: a microcontroller with real-time clock, a unique electronic identification number, an external barcode identification label, and an automatic locking mechanism that can be released electronically and controlled by the microcontroller. The microcontroller also preferably keeps track of dispense and fill requests and inventory. In a preferred embodiment, the small items being dispensed are pills.
