Abstract: A method for tracking status of an inventory shipment sent to a recipient includes monitoring whether the recipient has transmitted an electronic acknowledgment of the status of the shipment; and automatically transmitting a message to the recipient requesting acknowledgment of receipt of inventory if the electronic acknowledgment is not transmitted by the recipient within a first predetermined amount of time.

Abstract: A mobile telephone having a single piece molded housing or shell includes a core assembly for supporting the functional components of the mobile telephone. The core assembly may further include ancillary hardware components such as an electrical power source, user interface input/output devices, and the like required for operation of the telephone. The single piece molded shell molded about the core assembly so that the core assembly is substantially enclosed by the shell.

Abstract: A motor control system is provided for controlling at least one motor driven mechanical actuator. The control system drives the motor according to a function of the actuator position. The system is further arranged to modify the motor speed to ensure that a predetermined power limit is not exceeded.

Abstract: A strip-like microneedle device is provided that includes an array of hollow microneedles, a diaphragm pump to extract interstitial fluid from skin, and a sensor that detects the concentration of the fluid. The microneedle device can be interfaced to an external sensor to produce a reading, or can be self-contained. One version uses an attachable/detachable microneedle array as a single-use, disposable unit. The device is portable, and is used by placing one finger on the microneedle array, and actuating the diaphragm pump with another finger, thereby obtaining the fluid sample. Solid coated or transparent microneedles could instead be used as an in-situ sensor, with either electrodes or an optical sensor.

Abstract: An array of hollow microneedles is constructed of molded plastic, in which a micro-machining technique is used to fabricate the molds used in a plastic microforming process. The molds are detachable and can be re-used. The preferred process for making the plastic arrays of microneedles is a microinjection technique. In the microinjection method, a molten plastic substance is injected between two micro-machined molds that contain microhole and micropillar arrays. Once the desired shape of the microneedle array has been formed, the mold and the plastic material are cooled down. Next, the molds are separated and the plastic microneedle array is detached from the mold structures.

Abstract: A method for manufacturing microneedle structures is disclosed using soft lithography and photolithography, in which micromold structures made of a photoresist material or PDMS are created. The micromold manufacturing occurs quite quickly, using inexpensive materials and processes. Once the molds are available, using moldable materials such as polymers, microneedle arrays can be molded or embossed in relatively fast procedures. In some cases a sacrificial layer is provided between the forming micromold and its substrate layer, for ease of separation. The microneedles themselves can be solid projections, hollow “microtubes,” or shallow “microcups.” Electrodes can be formed on the microneedle arrays, including individual electrodes per hollow microtube.

Abstract: A microneedle array is manufactured using a mold preparation procedure that begins by placing an optical mask over a layer of PMMA material, exposing the PMMA material to x-rays, then developing using a photoresist process. The remaining PMMA material is then electroplated with metal. Once the metal has reached an appropriate thickness, it is detached to become a metal mold that is used in a microembossing procedure, in which the metal mold is pressed against a heated layer of plastic material. Once the mold is pressed down to its proper distance, the plastic material is cooled until solidified, and the mold is then detached, thereby leaving behind an array of microneedles.

Abstract: A multiple scent-containing article of manufacture for dispensing multiple scents into the environment wherein a number of the scents in the article are related to each other is disclosed. In one variation, the scents are selected from a group of different types of scents. In another variation, certain of the scents, or all of the scents, can be related to each other in that they share a common theme.

Abstract: A first embodiment microneedle array is constructed of silicon and silicon dioxide compounds using MEMS technology and standard microfabrication techniques to create hollow cylindrical individual microneedles. The resulting array of microneedles can penetrate with a small pressure through the stratum corneum of skin to either deliver drugs or to facilitate interstitial fluid sampling through the hollow microneedles into the epidermis. The delivery of drugs and sampling of fluids can be performed by way of passive diffusion (time release), instantaneous injection, or iontophoresis. In a second embodiment, an array of hollow (or solid) microneedles is constructed of plastic or some other type of molded or cast material. An electric field may be used to increase transdermal flow rate, and the microneedles can be effectively combined with the application of an electric field between an anode and cathode attached to the skin which causes a low-level electric current.

Abstract: A glitch removal circuit is disclosed that removes negative glitches from those signals that are provided to circuit elements that are turned-on by negative glitches (e.g., p-channel transistors), and/or removes positive glitches from those signals that are provided to circuit elements that are turned on by positive glitches (e.g., n-channel transistors). The positive glitches need not be removed from those signals that are provided to the circuit elements that are turned-off by positive glitches (e.g., p-channel transistors), and the negative glitches need not be removed from those signals that are provided to circuit elements that are turned-off by negative glitches (e.g., n-channel transistors). An advantage of the present invention is that both positive and negative glitches can be removed in parallel, rather then serially. This can significantly increase the performance of some circuits, and may reduce the amount of glitch removal circuitry required.

Abstract: One embodiment of a microneedle array is constructed of silicon and silicon dioxide compounds using MEMS technology and standard microfabrication techniques to create hollow cylindrical individual microneedles. The resulting array of microneedles is designed to penetrate the stratum corneum and epidermis layers of skin, but not into the dermis. In a second embodiment, an array of hollow (or solid) microneedles are constructed of molded plastic, in which a micro-machining technique is used to fabricate the molds used in a plastic microforming process. Such molds contain a micropillar array and/or microhole array. The manufacturing procedures for creating plastic arrays of microneedles include: “self-molding,” micromolding, microembossing, and microinjection techniques. In the “self-molding” method, a plastic (e.g.

Abstract: A microneedle array is constructed of silicon and silicon dioxide compounds using MEMS (i.e., Micro-Electro-Mechanical-Systems) technology and standard microfabrication techniques. The microneedle array may be fabricated from a silicon die which can be etched in a microfabrication process to create hollow cylindrical individual microneedles. The resulting array of microneedles can penetrate with a small pressure through the stratum corneum of skin (including skin of animals, reptiles, or other creatures—typically skin of a living organism) to either deliver drugs or to facilitate interstitial fluid sampling through the hollow microneedles.

Abstract: The present invention is directed to a large-pore aluminosilicate molecular sieve comprising alumina and silica, where the ratio of SiO2/Al2O3 ranges from about 75 to 600, and its method of preparation. The large-pore aluminosilicate molecular sieve of the present invention has the ability to catalyze reactions involving particularly bulky transition states or large molecules.

Abstract: A semiconductor device is disclosed that eliminates at least one of the channel/dielectric interfaces along the side walls of an SOI/SOS transistor channel, but does not require the use of a dedicated body tie contact. Because a dedicated body contact is not required, the packing density of the device may be significantly improved over conventional T-gate and H-gate configurations. The present invention may also reduce the overall gate area, which may increase both the speed and overall yield of the device.
