Title: Method and apparatus for guiding movement of a freely roaming animal through brain stimulation
Inventor: CHAPIN JOHN K
IPC: G06N3/06
Filed: 2003-02-10
Abstract: Movement of a freely roaming animal (190), such as a rat, is guided using electric stimulation of the animal's brain. Cues are provided to the animal to move forward by stimulating a reward center of the brain. Cues are provided to the animal to change its direction by stimulating portions of the animal's brain that control right and left movements, such as a cortical representation of whiskers of the animal. Multi-channel, remotely controlled equipment (140, 145, 150, 350) may be carried by the animal to enable independent energizing of electrodes attached to different regions of the animal's brain. A  transmitter carried by the animal may report back data to allow monitoring. A  component may be carried by the animal for carrying out a mission, such as for search and rescue or surveillance. Groups of animals may be controlled in real-time by coordinating their movements and tracking their locations.

Abstract: A sulfonic acid type organic surfactant is incorporated into the gelled anode mixture of an alkaline electrochemical cell, optionally with an organic phosphate ester surfactant. Zinc fines may also be incorporated into the anode. The electrolyte included in the anode mixture may have a reduced hydroxide concentration. When a cell is provided whose anode mixture includes the two surfactants and zinc fines alone or in combination with a lowered hydroxide concentration in the electrolyte, discharge leakage is reduced and gel gassing is suppressed relative to that of gels lacking both surfactants.  Additionally, cell discharge performance is improved relative to that of cells lacking both the zinc fines and lowered hydroxide concentration.

IPC: G06F19/00
Filed: 2003-04-04
Abstract: A method of identifying endmember spectral values from multispectral image data, where each multispectral data value is equal to a sum of mixing proportions of each endmember spectrum. The method comprises the steps of processing the data to obtain a multidimensional simplex having a number of vertices equal to the number of endmembers. The position of each vertex represents a spectrum of one of the endmembers. Processing the data is conducted by providing starting estimates of each endmember spectrum for each image data value. The mixing proportions for each data value is estimated from estimates of the spectra of all the endmembers. The spectrum of each endmember is estimated from estimates of the mixing proportions of the spectra of all the endmembers for each image data value. The estimation steps are repeated until a relative change in the regularised residual sum of squares is sufficiently small. The regularised residual sum of squares includes a term which is a measure of the size of the simplex.

Filed: 2003-06-30
Abstract: The invention concerns a pressure sensor with temperature compensated optical fiber for detecting pressure variations in at least one environment relative to a reference environment such as atmosphere or an environment where a counter-pressure prevails. The sensor essentially comprises a deformable element (2) such as a bellows (5) exposed on one side to the reference environment and on the side opposite to the pressure to be measured, an optical fiber portion (F1) including at least one optical grating such as a Bragg grating (B1), which is connected on the side of the deformable element (2) and on the side opposite to the pressure to be measured to a fixed point. The optical fiber portion is prestressed by a device (6, 15, 20, 21) and its elongation varies with the displacements of the deformable element. The device prestresses the optical fiber portion (F1) between the deformable element (2) and another fixed element (15) isolated from the environment by a rigid housing (1). An optical system (25) detects the deformations sustained by said optical grating in response to the pressure variations sustained by the deformable element. Another part (F2) of the optical fiber not subjected to stresses (or another non-stressed portion of the fiber connected to the first), preferably comprises another similar optical grating (B2) enabling likewise measurement of temperature variations. By duplicating the deformable elements and optionally the stress applying device (3), differential pressure variations can be measured as well. Such a sensor can in particular be used for measuring pressure and temperature in wells where difficult conditions prevail.
