摘要:
An adjustment mechanism for a helmet. A first sliding surface is defined in a first portion of the helmet and includes an opening. A second sliding surface is defined in a second portion of the helmet. Two spaced apart arms extend from the second sliding surface. The first and second sliding surfaces are in sliding engagement with one another with the arms sliding within the opening. A lever is pivotally connected to the first portion in proximity of the opening and pivotable between a locked position and an unlocked position. The lever has a series of regularly spaced apart parallel teeth which in the locked position protrude through the opening with at least a selected one of the teeth being engageable between the two spaced apart arms to prevent the first and second sliding surfaces from sliding relative to one another.

A hinge mechanism for attaching ear accessories to a helmet allows an accessory to be attached at a point outside the helmet shell utilizing, for example, a slidable mounting rail, and to reach under the edge of the helmet shell so that the accessory is supported in contact with the wearer's head. The hinge mechanism is well suited for use in connection with military helmets that have a “bulge” or protrusion over the ear.

An improved headband provides adjustment to fit the shape and size of the wearer's head as well as stand-off from the inner surface of the helmet shell. When the wearer's head is fitted properly in the headband, the headband desirably resists displacement toward the helmet shell in all directions.

An improved retention system for a protective helmet comprises slide/coupling mechanisms on opposite sides of the helmet shell, and a movable element at the rear of the helmet. Fastening of the chinstrap secures the helmet in the downward direction and tightens the movable element against the nape of the neck, thereby securing the helmet in the area of the occipital lobe.

An implantable drug delivery device is provided with a passive flow control device is provided in the form of a valve which may assume two flow states. Flow control is achieved by duty cycling the valve using a control module which generates appropriate signals in response to an input telemetry signal corresponding to a desired flow rate. In another embodiment, a passively controlled bolus delivery device is provided to deliver a bolus of drug in addition to normal dosage.

A three-part cabinet latch, a first part of which is relatively rigid, is attached to the cabinet door and has a hook shaped portion on one end. Another part is relatively resilient, is attached to the cabinet floor and has a hook shaped end which cooperates with the hook shaped portion on the first part to hold the door closed. A third part of the cabinet latch is a quick- release pin installed through a hole in the cabinet floor, and when pushed up will force the resilient second part to release from the first part so the door can be opened.
摘要:
A system for monitoring an implantable medical device. The system includes an implantable therapeutic substance delivery device for delivering a therapeutic substance, along with a temperature sensor and an indicator device. The delivery device includes a housing maintaining a reservoir for containing the therapeutic substance. Further, the delivery device includes a fill port assembly having a port chamber in fluid communication with the reservoir and including a septum fluidly sealing the chamber. The temperature sensor is associated with the fill port assembly. Finally, the indicator device is adapted to indicate presence of a needle within the port chamber based upon information from the temperature sensor.

Method of controlling an implantable medical device having a power source having a voltage, a therapeutic substance pump driven by a motor, electrically coupled to the power source, supplied with a series of drive pulses having a duty cycle. The voltage of the power source is measured. The duty cycle of drive pulses to the motor are varied by increasing the duty cycle as the voltage of the power source decreases.

A programmable delay in an AFE of an imaging system which can vary both the pulse position and the pulse width. The pulse width and position are controlled by providing separate programmable delay circuits for the rising and falling edges of the desired timing signal. Combining logic then combines the outputs of the two delay circuits to produce an output clock with separately delayed rising and falling edges.

A vehicle attachment that sits behind a vehicle and attaches to the vehicle's trailer hitch. To the plate is attached a device such as a barbecue, tool, etc. The plate is attached to a series of tubular members that connect to one another and ultimately to the vehicle's trailer hitch. The plate is easily removed, allowing the user to either use the plate or to easily attach other attachments to the hollow pole. Therefore, the user can quickly and easily perform a variety of activities at variable heights behind the vehicle.
