Abstract: By use of the vias a microfluidic autoregulator is fabricated comprising an origin of a fluid, a sink for the fluid, a main flow channel coupling the origin and the sink, a valve communicated to the main flow channel to selectively control flow of fluid therethrough, and means dependent on flow through the main flow channel for creating a pressure differential across the valve to at least partially activate the valve to control flow of fluid through the main flow channel. The means for dependent on flow for creating a pressure differential comprises either a dead-end detour channel from the flow channel to the valve, or a loop channel fed back to the control chamber of the valve.

Abstract: A biosensor is comprised of a free and a biofunctionalized recognition self-sensing nanocantilever, a dock adjacent to the ends of the nanocantilevers, and a gap between the nanocantilevers and dock. The self-sensing cantilevers each include a semiconductor piezoresistor defined in a pair of legs about which the cantilevers flex. A bias power or current is applied to the piezoresistor. The sensitivity of the cantilevers is optimized for a given ambient temperature and geometry of the cantilevers and dock by minimizing the force spectral density, SF, of the cantilevers to determine the optimum bias power, Pin. A sub-aN/?Hz force sensitivity is obtained by scaling down the dimensions of the cantilevers and supplying an optimum bias power as a function of temperature and geometry.

Abstract: Gas flows of modest velocities are generated when an organized ion flux in an electric field initiates an ion-driven wind of neutral molecules. When a needle in ambient air is electrically charged to a potential sufficient to produce a corona discharge near its tip, such a gas flow can be utilized downstream of a ring-shaped or other permeable earthed electrode. In view of the potential practical applications of such devices, as they represent blowers with no moving parts, a methodology for increasing their flow velocities includes exploitation of the divergence of electric field lines, avoidance of regions of high curvature on the second electrode, control of atmospheric humidity, and the use of linear arrays of stages, terminating in a converging nozzle. The design becomes particularly advantageous when implemented in mesoscale domains.

Abstract: An alternative to a real time operating system (RTOS) is provided based on serializing compilers. A serializing compiler can transform a multitasking application into an equivalent and optimized monolithic sequential code, to be compiled with the embedded processor's native optimizing compiler, effectively filling the RTOS gap. The serializing compiler can analyze the tasks at compile time and generate a fine-tuned, application specific infrastructure to support multitasking, resulting in a more efficient executable than one that is intended to run on top of a generic RTOS. By having control over the application execution and context switches, the serializing compiler enables the fine grain control of task timing while enhancing overall performance. The serializing compiler technology strengthens existing compilers, making them timing and task-aware.

Abstract: The illustrated embodiment of the invention is an apparatus for use in bonding a plurality of brackets and/or tubes to a specific patient's teeth which includes a resilient orthodontic indirect bonding tray having at least one lingual surface. The plurality of brackets and/or tubes is selectively arranged and configured in the tray for bonding to the specific patient's teeth. At least one standoff is disposed in the tray to urge the lingual surface of the tray away from the teeth while the lingual surface is passing over the teeth and prior to the tray assuming an intended final position.

Abstract: A brake pad measuring device is designed to be small enough to fit through various suspension components or many vehicles' wheel aperture and still maintain the ability to move in three-dimensions. The device is compact enough so that it may take an accurate reading of the thickness of a brake pad while being between the caliper housing and the brake pad backing plate of a vehicle. The device also comprises a spring so that once it is correctly placed, it may be manipulated in order to automatically get a reading of the thickness of a brake pad to the closest millimeter or 32nd of an inch by releasing the spring to cause a measurement to be automatically taken. Using this device, any user can get quick, reliable measurements for all four sets of brake pads in a matter of minutes and all without having to remove a single wheel from the vehicle.

Abstract: The invention relates to an oven (1) comprising a preparation space and a device for heating the content thereof, and further provided with means for releasably connecting steam module (18) to the heating device. In this way a convection oven may be converted into a steam oven. The heating device may be arranged in a housing (4), and the connecting means may comprise attachment points (19, 20) arranged on an outer wall of the housing for parts of the steam module (18), like a condenser (31), supply and discharge valves (34, 35) and a pressure sensor (36).

Abstract: A magnetically controlled pump is implanted into the brain of a patient and delivers a plurality of medicating agents at a controlled rate corresponding to the specific needs of the patient. The current invention comprises a flexible double walled pouch that is formed from two layers of polymer. The pouch is alternately expanded and contracting by magnetic solenoid. When contracted, a medicating agent is pushed out of the pouch through a plurality of needles. When the pouch is expanded, surrounding cerebral fluid is drawn into the space between the double walls of the pouch from which it is drawn through a catheter to an analyzer. Cerebral fluid drawn from the patient is analyzed. The operation of the apparatus and hence the treatment is remotely controlled based on these measurements and displayed through an external controller.
