Title: Control system for atomizing liquids with a piezoelectric vibrator
Inventor: CLARK GEORGE A
IPC: B05B17/00
Filed: 2000-03-06
Abstract: There is described a battery driven atomizer in which an alternating voltage is applied to a piezoelectric actuation element (10) to cause it to expand and contract and vibrate an atomizing orifice plate. The alternating voltage is controlled to produce a high amplitude vibration during a first portion of a drive period, to initiate atomization, and thereafter to produce a lower amplitude vibration to sustain atomization during the remainder of the drive period. The frequency of the alternating voltage is swept repeatedly during each drive period.

Title: Direct current motor safety circuits for fluid delivery systems
Inventor: MOBERG SHELDON B
IPC: H02P7/288
Filed: 2000-06-16
Abstract: A safety circuit system for a DC driven device for use with a fluid delivery system includes a first voltage potential DC power line, a second voltage potential DC power line, a controller and a safety circuit. The first voltage potential DC power line is coupled to provide a first voltage potential to the DC driven device, and the second voltage potential DC power line is coupled to provide a second voltage potential to the DC driven device such that the second voltage potential is different relative to the first potential. The controller controls at least the first voltage potential on the first voltage potential DC power line. The safety circuit has an enable state and a disable state, in which the default state is the disable state. The safety circuit is coupled to the controller, and the controller controls the safety circuit to place the safety circuit in the enable state independently of controlling the first voltage potential on the first voltage potential DC power line. The safety circuit is operatively coupled to at least one of the first and second voltage potential DC power lines to inhibit DC flow and operation of the DC  driven device when the safety circuit is in the disable state and to permit DC  flow and operation of the DC driven device when the safety circuit is in the enable state such that the operation of the DC driven device will occur when the safety circuit is in the enable state. In one version the DC driven device is a DC motor in an infusion pump, while in other versions the DC driven device is a gas generator in an infusion pump. Preferably, the safety circuit is controlled by an AC signal from the controller such that the safety circuit is enabled by the AC signal to permit DC flow and enable the forward motion of the DC motor while the AC signal is provided by the controller.

Title: Improved cathode structures for direct liquid feed fuel cells
Inventor: MULLER JENS
IPC: H01M8/10
Filed: 2000-11-07
Abstract: Direct liquid feed solid polymer fuel cells are supplied with a liquid fuel stream typically comprising a mixture of fuel and a substantial amount of water (for example, liquid feed direct methanol fuel cells). The oxidant stream supplied however is typically a gaseous stream (for example, air) as is commonly supplied to gas feed solid polymer fuel cells. A greater amount of water typically diffuses from the anode side to the cathode side in liquid feed cells, thereby having an effect on water management at the cathode. A  different cathode structure having a lesser amount of hydrophobic additive in the cathode substrate is preferred in liquid feed fuel cells. Further, a thinner cathode may be used without sacrificing fuel cell performance, by using a combination of a thinner carbonaceous support in the cathode substrate and a carbon-based sublayer between the cathode substrate and electrocatalyst layer.

Patent CA-2416412-A1 (CA)
Inventor: SARUNIC MARINKO VENCI
IPC: G03F1/08
Filed: 2001-07-17
Abstract: A thermal inorganic resist useful for lithographic processes and image creation is created by depositing on a substrate at least two layers of materials which are typically metals. The materials form a mixed alloy with a eutectic. One embodiment has a 15 nm Bi layer overlying a 15 nm In layer. Upon exposure to a optical light pulse of sufficient intensity, optical absorption heats the layers above the eutectic melting point (110~ C for BiIn) and the resist forms an alloy in the exposed area. By selectively heating parts of the resist a desired pattern can be created in the resist. Optical characteristics of the alloyed layers are typically different from those of the unexposed layers. In BiIn resists the alloyed areas are visually transparent compared to the unexposed sections. The exposed pattern provides a viewable image useful for exposure control. In a negative resist the alloy material is resistant to development etches which remove the unexposed areas but only slowly etch the alloyed areas creating a lithographic structure. This resist structure can be used to pattern layers below it in additional etches. The resist layer can then be stripped, leaving the pattern layer on the substrate. In resists showing significant optical differences (such as BiIn) after exposure this same material can be used to create images for data storage, and, when transparent, photomasks for optical lithography.
