A delivery device includes a durable housing portion and a separable disposable portion that selectively engage and disengage from each other. The disposable housing portion secures to the patient-user and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient-user or with infusion media are supported by the disposable housing portion for disposal after the prescribed use, while the durable housing portion supports other components such as electronics for controlling delivery of infusion media from the reservoir and a drive device and drive linkage.

The present invention provides a subsonic ammunition including a polymeric casing body comprising a generally cylindrical hollow polymer body having a body base at a first end thereof and a mouth at a second end to define a propellant chamber; a propellant insert positioned in the propellant chamber to reduce the internal volume of the propellant chamber, wherein the propellant chamber has an internal volume that is between 25 and 80% less than the open internal volume of a standard casing of equivalent caliber; a propellant disposed and confined within the propellant chamber; a primer insert positioned at the body base and in communication with the propellant chamber; a primer disposed in the primer insert in combustible communication with the propellant; and a projectile frictionally fitted in the mouth in combustible communication with the propellant.

The present invention provides a subsonic ammunition cartridge including a polymeric casing body comprising a generally cylindrical hollow polymer body having a body base at a first end thereof and a mouth at a second end to define a propellant chamber; a propellant insert positioned in the propellant chamber to reduce the internal volume of the propellant chamber, wherein the propellant chamber has an internal volume that is between 25 and 80% less than the open internal volume of a standard casing of equivalent caliber; and a primer insert positioned at the body base and in communication with the propellant chamber.

An apparatus, system and method for regulating fluid flow are disclosed. The apparatus includes a flow rate sensor and a valve. The flow rate sensor uses images to estimate flow through a drip chamber and then controls the valve based on the estimated flow rate. The valve comprises a rigid housing disposed around the tube in which fluid flow is being controlled. Increasing the pressure in the housing controls the size of the lumen within the tube by deforming the tube, therefore controlling flow through the tube.

A system includes a durable portion with a durable housing and a separable disposable portion with a disposable housing that selectively engage with and disengage from each other. The disposable housing secures to a patient and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient or with an infusion medium may be part of the disposable portion to allow for disposal after a prescribed use. A reservoir for holding the infusion medium may be part of the disposable portion, and may be supported by the disposable housing. The durable portion may include other components such as electronics for controlling delivery of the infusion medium from the reservoir, and a drive device including a motor and drive linkage.

A flow meter includes a coupler, a support member, an image sensor, and one or more processors. The coupler is adapted to couple to a drip chamber. The support member is coupled to the coupler. The image sensor has a field of view and is operatively coupled to the support member. The image sensor is positioned to view the drip chamber within the field of view. The processor is operatively coupled to the image sensor to receive image data from the image sensor and is configured to: capture an image of a drip chamber using an image sensor; compare the image of a drip chamber with a dynamic background image; and adjust a flow rate of fluid flowing through the fluid line in accordance with the comparison between the image of the drip chamber and the dynamic background image.

A plastic container comprises an upper portion including a finish adapted to receive a closure, a lower portion including a base, and a sidewall extending between the upper portion and the lower portion. The upper portion, the lower portion, and the sidewall define an interior volume for storing liquid contents. The plastic container further comprises a pressure panel located on the container and moveable between an initial position and an activated position. The pressure panel is located in the initial position prior to filling the container, and is moved to the activated position after filling and sealing the container. Moving the pressure panel from the initial position to the activated position reduces the internal volume of the container and creates a positive pressure inside the container. The positive pressure reinforces the sidewall. A method of processing a container is also disclosed.

A connector system for Behind-The-Ear (BTE) hearing devices provides a means to detachably connect a plurality of earhooks, which earhooks include special earhooks providing auxiliary functions. The connector system includes a coaxial connector mounted on the BTE device, which coaxial connector provides both an earhook mounting fixture, and an electrical connector for auxiliary functions. The auxiliary functions include a telecoil, an auxiliary microphone positioned proximal to an ear canal, an FM receiver, and an input jack for miscellaneous devices. The earhook mounting fixture also accepts standard off-the-shelf earhooks. A friction fit is provided between the earhook and the BTE device so that the angular position of the earhook may be adjusted for a comfortable fit.

A substrate processing apparatus including a frame, a first SCARA arm having an end effector and being configured to extend and retract along a first axis, a second SCARA arm having an end effector and being configured to extend and retract along a second axis, a drive section including a splitting drive pulley rotatably mounted to rotate at an axis of rotation of the drive section that is shared by the first and second SCARA arms, the splitting drive pulley being coupled to at least two idler pulleys by respective segmented transmission loops of separate band segments so that the splitting drive pulley is a common pulley splitting one degree of freedom of the drive section between the at least two idler pulleys so as to commonly drive the at least two idler pulleys, wherein at least one band of each respective transmission loop share a common band interface level.

An evaporator with a cool storage function includes a cool storage material container disposed at least one of air-passing clearances formed between adjacent refrigerant flow tubes, and fins disposed in air-passing clearances on opposite sides of the cool storage material container. The cool storage material container includes a container body portion joined to the corresponding refrigerant flow tubes, and an outward extending portion which extends from the front edge of the container body portion and projects frontward in relation to the refrigerant flow tubes. Each of the fins has a fin body portion joined to the corresponding refrigerant flow tubes, and an outward extending portion which extends from the front edge of the fin body portion body and projects frontward in relation to the refrigerant flow tubes. The outward extending portions of the fins are brazed to opposite sides of the outward extending portion of the cool storage material container.

A duffel bag can be reversibly converted to a cross-over bag by restricting the storage volume of the bag at one end. Optionally, a carrying strap may be adjusted from a central anchor to an outer anchor to facilitate draping the carrying strap over a shoulder.

The present invention relates to a metered drop bottle for dispensing microliter amounts of a liquid in the form of a drop comprising: (a) a bottle with a flexible portion on the walls to decrease the internal volume by a fixed volume; (b) a plunger with a fixed stroke for depressing the flexible portion of the walls of the bottle; and (c) a nozzle tip having an internal and/or outer diameter no more than 1.2 mm.
