Abstract: An electronic sign employs a bi-stable, non-volatile display material activatable by electrodes to convey information. A sensor detects when the electronic sign is inserted in or in the vicinity of an insertion area, and controls the operation of the sign based on the detected location. A backplane in the electronic sign includes different patterns of addressable elements to provide a display that pixel, font region, or icon addressable or have a combination of one or more of the pixel, font region, or icon addressability. A remote device communicates with the electronic sign, and multiple electronic signs may communicate with each other via a communication protocol, such as mesh networking.

Abstract: A method of associating a resource attribute and a discussion topic is disclosed. In one embodiment, the method includes, in an end station, in response to display of at least one of a resource and a topic, and following user input indicative of a create association request, generating an association request indicative of a topic and at least one resource attribute. The association request is transferred to a base station, which is responsive to the association request to generate association data indicative of the association between the resource attribute and the topic.

Abstract: A novel application of independent component analysis (ICA) to data acquired by a single sensor. The technique exploits the unique relationship between multiple physiologic (source) and electronic (artifact) components in surface recorded sensory nerve action potential (SNAP) waveforms that are evoked by different activating magnitudes. A forward model of the SNAP is developed and used to test the approach on a simplified data simulation. The method is applied to experimental data and shown to be effective at separating artifact and source components and reconstructing artifact-free traces. A method of automated reconstruction for use within an expert system is also disclosed.

Abstract: A theft detection system includes an accelerometer attachable to an object, the accelerometer providing an acceleration signal in response to movement of the object; an alarm mechanism for providing a signal in response to movement of the object; and for preventing false alarms, a filter programmed to determine the frequency of the acceleration signal and to provide an output to activate the alarm mechanism only when the frequency of the acceleration signal meets a predetermined criteria.

Abstract: The present invention is directed to improved systems and methods for distinguishing and classifying subjects based on analysis of biological materials. Methods for the analysis of multivariate data collected from a plurality of subjects of known class are provided. The results of such analyses include a set of intermediate combined classifiers as well as a metal variable that relates directly to the classes of the subjects in a training population. Both the intermediate combined classifiers and the final meta model are used to distinguish and classify subjects of previously unknown class.

Abstract: An apparatus and method for the transduction, acquisition, and processing of physiologic variables are described. The apparatus is a self-contained, patient-worn device consisting of a flexible substrate, a transduction means, a power generation means, and a signal acquisition and processing means, and a data transmission means.

Abstract: A motion password control system including a motion sensor responsive to motion of a device and providing a signal corresponding to movement of the device; a database including stored data values corresponding to predetermined motion of the device; and an electronic circuit, responsive to the motion sensor, configured to compare the motion sensor signal with the stored database values, and, in response, to provide an output signal for performing at least one action of a preselected set of actions when the comparison reveals that the device has moved in a way which corresponds to the stored data values.

Abstract: A liquid fabric softening composition contains(i) an aqueous base;(ii) a water-insoluble cationic fabric softener such as a quaternary ammonium salt or an imidazolinium salt;(ii) a nonionic material having an HLB of not more than 10 such as fatty acids, fatty esters of monohydric or polyhydric alcohols and fatty alcohols, the ratio of the cationic to nonionic materials being less than 5:1; and(iv) an electrolyte selected from salts of lithium, calcium, magnesium and aluminium.The specified electrolytes improve the stability of the composition.

Abstract: A fabric conditioning composition comprises a fabric conditioning agent including a cationic fabric softening material, together with an inorganic material capable of precipitating a metal hydroxide or hydrated oxide at a pH of about 7.5 of less in water. The latter material is preferably aluminum chlorhydrate. A typical composition contains about 4% quaternary ammonium cationic fabric softener and from 0.5% to 1.5% aluminum chlorhydrate. The compositions are useful as rinse products and give improved fabric softness in the presence of anionic carry-over from the wash.

Abstract: The invention relates to the field of fabric softening. It provides for fabric softening compositions comprising a relatively water-insoluble cationic detergent surfactant and a free C.sub.8 -C.sub.24 alkyl- or alkenylmonocarboxylic acid. These compositions are significantly more storage stable than compositions, wherein the monocarboxylic is present as a soap. Further inclusion of a relatively water-soluble cationic detergent surfactant or cationic polymer significantly increases the softening performance.

Abstract: A pourable, stable, liquid fabric-softening composition comprises an aqueous dispersion of particulate softening agent which comprises an quaternary ammonium salt having one straight-chain aliphatic hydrocarbon radical, complexed with an anion of an anionic surfactant in a normality ratio of 1.1:1 to 5:1.

Abstract: Fabric softening is provided by cationic diesters of the formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are each an alkyl or hydroxyalkyl group containing from 1 to 4 carbon atoms, or a benzyl group, R.sub.4 and R.sub.5 are each alkyl chains containing from 11 to 23 carbon atoms, and X.sup.- is a water soluble anion. Mixtures of these diesters with the corresponding monoesters are described together with preparative methods.
