Granted: 2008-12-02
Abstract: A de-agglomerator is provided for use with a breath-actuated dry powder inhaler for breaking up aggregates and micronizing particles of dry powder prior to inhalation of the powder by a patient using the inhaler. The de-agglomerator includes an inner wall defining a swirl chamber extending along an axis from a first end to a second end, a dry powder supply port, an inlet port, and an outlet port. The supply port is in the first end of the swirl chamber for providing fluid communication between a dry powder delivery passageway of an inhaler and the first end of the swirl chamber. The inlet port is in the inner wall of the swirl chamber adjacent to the first end of the swirl chamber and provides fluid communication between a region exterior to the de-agglomerator and the swirl chamber. The outlet port provides fluid communication between the second end of the swirl chamber and a region exterior to the de-agglomerator, whereby a breath induced low pressure at the outlet port causes air flows into the swirl chamber through the dry powder supply port and the inlet port. The air flows collide with each other and with the wall of the swirl chamber prior to exiting through the outlet port, such that any powder entrained in the air flows is broken down and micronized. The de-agglomerator further includes vanes at the first end of the swirl chamber for creating additional collisions and impacts of entrained powder.

Abstract: The present invention provides a pancreas induced in vitro which enables to obtain knowledge regarding the mechanisms of differentiation and formation of pancreas that is useful for developmental engineering and organ engineering, and organ engineering, a pancreas for transplantation by which it can be evaluated whether or not a pancreas induced in vitro can function in practice in vivo, and a method wherein a pancreas induced in vitro which contributes to the development of diagnosis and treatment of pancreas disorder for higher animals, can artificially and efficiently be induced from a gastrula apart from the presumptive region of pancreas. Pancreas is formed in vitro by treating the blastopore upper lip of an early gastrula of a vertebrate such as Xenopus with retinoic acid in vitro, and then culturing. The treatment with retinoic acid can be carried out, for example, by treating with retinoic acid at a concentration of 10-5 M or above for three hours.

The algorithm and/or method can be recorded in a computer program or on a data carrier. Also disclosed is a method of determining said weighting factor. The invention further provides a method and apparatus for subsurface surveys in which electromagnetic pulse signals are emitted. All the necessary response signal samples are taken from each response signal received, and these are converted into a response signal word in order to characterize the response signal. Successive response signal words are buffered to form a data word in order to provide an image of the subsurface structure. Figure 3.

Title: Roll sensor system for a vehicle
Inventor: MILLER MICHAEL L
IPC: G01C19/00
Filed: 2003-03-11
Granted: 2009-01-27
Abstract: A roll sensor system for a land vehicle is provided to determine when a vehicle roll condition has occurred and to trigger a safety system in response to that determination. In certain embodiments, an angular rate sensor is used to obtain an angular rate and, from the angular rate, an angle relative to the roll axis of the land vehicle. If the angular rate and the angle correspond to a safety system activation event, the roll sensor system will provide a trigger signal to the safety system. In some embodiments, the system includes an incline sensor(s) to aid in detecting and compensating for drift in the output of the angular rate sensor. In other embodiments the output of an angular rate sensor is used to validate the output of the incline sensor to aid in determining whether a vehicle safety system trigger event has occurred.
