A traffic information system includes a traffic information server linked to a mobile terminal via a supporting wireless communications network. The traffic information system provides traffic information pertaining to a learned route of travel to a user of the mobile terminal when it is recognized that the user is likely traveling or is likely to travel on the learned route of travel. Routes of travel are learned based on tracking the location of the mobile terminal while traveling a specific route of travel, or over time to identify commonly traveled routes. Recognizing that the user is traveling on or is about to travel on a learned route may entail recognizing that a current time matches a customary travel time for the learned route. Alternatively, or in combination, such recognition may entail recognizing that a current location of the mobile terminal matches a location associated with the learned route.

A composition for cryopreservation of cells and tissues of human and other animals in a safe manner without using toxic substances such as DMSO, as well as for freeze preserving or freeze-drying of foods and pharmaceuticals. In examples, ε-poly-L-lysine is reacted with succinic anhydride so that 60% or more of amino groups are blocked; and, thus obtained polymer compound is added to Dulbecco-modified eagle MEM culture medium (DMEM) on market sale to form a cryopreservation liquid. In examples for foods or pharmaceuticals, the ε-poly-L-lysine derivative was added by 0.5-10 wt % to curb freeze concentration.

Devices and methods for the characterization of areas of radiation in contaminated rooms are provided. One such device is a collimator with a collimator shield for reducing noise when measuring radiation. The determination system uses a radiation detector comprising a plurality of overlapping layers of radiation sensitive film interspersed with adjacent layers of an attenuator material. The resulting sandwich of the stacked film layers and attenuator layers provides a useful detector. The detector can be used within a radiation detector apparatus having a collimator to enable a 360 degree field of view of radiation sources within a room or enclosed environment.

This is accomplished by administration of a botulinum toxin into the lower urinary tract of a patient with urinary retention, including the bladder or urinary sphincter and the bladder wall.

The present invention related to methods for treating neurological-urological conditions, including neurogenic bladder dysfunction. This is accomplished by administration of a botulinum toxin into the lower urinary tract of a patient with a neurogenic bladder dysfunction, including the bladder or urinary sphincter and the bladder wall.

A skin cleansing device comprising includes two or more electrodes attached to the cleansing pad, a cleansing signal generator for generating an electric cleansing signal, and elements for conveying the cleansing signal from the cleansing signal generator to the electrodes. Electrode pairs include a positive electrode and a negative electrode located in the cleansing pad. The cleansing signal generator operates on low voltage direct current and generates a square wave alternating current cleansing signal with a voltage lower than 5V and frequency higher than 2000 Hz. The cleansing pad of the cleansing device has a sandwich construction, including at least a detachable absorbent layer receiving a cleansing solution to be arranged against the skin, a layer receiving the electrodes and an outer surface layer.

The present invention generally relates to a reusable personal heating system including a sealed container filled with a supercooled supersaturated solution and an activator located in a fixed position within the container which triggers an exothermic crystallization process when depressed. The removable and reusable personal heating system fits into a garment worn under other clothing and is easily activated through other clothing. The present invention provides a personal heating system that allows the wearer to participate in outdoor activities in cold conditions while permitting ease of mobility and range of motion.

Hydrating an object bearing a latent fingerprint and then selectively drying the object leaving the fingerprint hydrated. The hydrated fingerprint is then coated with cyanoacrylate ester, preferably in a heat accelerated cyanoacrylate ester vacuum chamber. Hydrating is preferably accomplished by chilling the object below a dew point and then exposing the object to humidified air to condense a thin uniform layer of water over the object and latent fingerprint. Drying is preferably done with a vacuum. After drying reaches the preferred state, the CE is heated and coats the condensation-hydrated latent fingerprint. Preferably, the method is implemented in an automated system using one computer-controlled chamber for chilling, condensing, vacuum drying, and CE coating the latent fingerprint. The operator simply puts the object in the chamber, initiates the process by computer, and is prompted by the computer to remove the recovered latent print. Prints unrecoverable by prior art means are recovered.

Apparatus for the inspection of cargo containers for nuclear materials comprising one or more arrays of modules comprising grounded, closed conductive tubes filled with an ionizing gas mixture such as, but not limited to, Argon:CO₂. A wire is suspended along each tube axis and electrically connected at both ends of the tube. A positive, dc high voltage is supplied to one end of the wire and an amplifier is attached to the other end through a capacitance to decouple the amplifier from the high voltage. X-rays, gamma rays or neutrons produced by nuclear material and passing through the tube ionize the gas. The electrons from the gas ionization process are accelerated toward the wire surface due to the wire's electrical potential. The acceleration of the electrons near the wire's surface is sufficient to ionize more gas and produce an amplification of electrons/ions that create a surge of current large enough to be detectable by the amplifier. Means are also provided for a warning device coupled to the amplifier.
