Abstract: Provided is an apparatus and method for the detection of dental caries. The apparatus generates longitudinal ultrasound waves that may be applied to any accessible surface of a tooth. The reflected ultrasound pulse echoes are collected and correlated with the incident pulse. The ultrasound pulse echoes from the front and rear surface of a dental cavity may be distinguished from other echoes, and provided in visual display to inform as to the size and location of the cavity.

Abstract: A system and a method for controlling the presentation of multimedia content. Multimedia content is provided to a plurality of multimedia devices, control signaling is sent to each of the plurality of multimedia devices, and responsive to the control signaling, each of the multimedia devices presents the provided multimedia content. The multimedia content provided to each multimedia device can alternatively be the same or coordinated (i.e. different) content. The control signaling can include indications as to which of the multimedia content to present, when to start presenting it, and when to stop presenting it. Responsive to the control signaling, each of multimedia devices can present one or more items of multimedia content. The coordinated presentation of multimedia content by the plurality of multimedia devices results in a collective form of multimedia presentation that goes beyond the presentation of the individual multimedia content items on each of the individual multimedia devices.

Abstract: The debridement of wounds, and particularly burn wounds, is more effectively accomplished by starting with a first substance comprising a mixture of collagenase and a non-aqueous excipient and a second substance comprising an aqueous excipient and, preferably, a cream such as an antibiotic cream, both of which substances have a satisfactory shelf life, and treating the wound by combining those two substances and promptly applying the resulting combination to the wound. Shelf life requirements are satisfied, and the effect of applying the resulting combination to the wound promptly after the combination has been formed results in a more effective debridement than would be expected from the application of other collagenase substances.

Abstract: The invention provides a distributed event notification mechanism that allows distributed applications to communicate with each other by generating events and receiving events through a distributed event notification service. An event manager coordinates activities between respective applications to ensure distribution regardless of the physical location of network elements. A naming service provides details of application location and configuration.

Abstract: A method is described for allocating buffers in a packet switched communication system offering different classes of service, each class of service being associated with a QoS queue. The optimal buffering is determined when a new packet for a particular QoS class arrives. The buffer limit is for the queue associated with said particular class in accordance with the determination, and new packet is handled according to the newly set buffer limit.
