摘要:
In one aspect of the invention, a container for displaying, preparing and presenting food including a base having an integrated cutter having a plurality of blades and a central hub and a cover removably attached to the base for displaying the food prior to use and for storing the food during and after cutting, the cover having indentations to receive the central hub and possibly the blades to enhance the depth of cutting by the cutter through the food. The base and cover have side walls dimensioned so that the cover interfaces with the base after driving.

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.

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.

A packaging system comprising a plurality of disposable cleaning heads, each of the plurality of cleaning heads including at least one cleaning substrate and a one-piece flexible fitment, the fitment including an engagement member adapted to removably engage a handle, and a shell having a bottom and a top, the top being hingedly connected to the bottom whereby said shell has an open position and a closed position, the bottom including a first cavity adapted to receive and retain at least one of the plurality of cleaning heads, the top including a second cavity adapted to receive and retain at least one of said plurality of cleaning heads. Preferably, the first and second cavities are adapted to receive and retain at least three of the plurality of cleaning heads.

The method of calibrating includes selecting discrete levels of cuff pressure and placing the artery under study at those discrete levels of induced pressure with a closed pneumatic cuff system, substantially continually sensing cuff pressures at each discrete level and thereby sensing blood volume change through the artery, electronically determining when a certain number of representative blood volume change signals are substantially equivalent, changing the volume in the closed pneumatic system at each discrete cuff pressure by a predetermined volumetric amount after determining substantial equivalency, and, correcting the blood volume change signal based upon the signals detected during the volume change of the closed pneumatic cuff system. The calibration device includes, in one embodiment, a controllable pneumatic pump, a pressure sensor, a computerized device for determining when a representative number of blood volume change signals (based on the pressure sensor signals) are substantially similar and thereafter generating a calibration trigger signal. The calibration system also includes a device which changes the volume in the closed pneumatic system by a predetermined calibrated volumetric amount upon application of the calibration trigger signal. This volume changing device may be a reciprocating piston.

摘要:
A liquid ventilator having a dual loop, single pump configuration is disclosed. The liquid ventilator preferably utilizes two three-way valves for routing liquid from a reservoir in a regeneration apparatus and to a patient's pulmonary system, and back to the reservoir again. A controller controls the configuration of the three-way valves and the pump speed of the motor to allow user control over the parameters of inspiration and expiration.
