Abstract: An AAL2/SSCS packet voice system multiplexes various forms of voice-band traffic including voice packets, fax packets, and data packets into a virtual circuit (VC). This AAL2/SSCS packet voice system executes a dynamic call admission algorithm that takes into account call type in deciding whether to admit a new call to the VC. In particular, this approach takes into account different bandwidth needs for different call types. The AAL2/SSCS packet voice system also performs bit or block dropping on voice packets to mitigate the effects of traffic congestion. The bit or block dropping is done based on the packet queue fill value exceeding at least one queue threshold. Further, the AAL2/SSCS packet voice system also dynamically varies a queue threshold as a function of capacity.

Abstract: A method for data transmission in a wireless communication network utilizes an on-demand multiple access method with a fair queuing service discipline for efficient utilization of the limited bandwidth available in the network by sharing bandwidth among the remote hosts. In one embodiment, the base station broadcaststhe system virtual time and the assigned shares of service classes to each of the wireless a Each remote host computes its own service tag and reports it to the base station, which assigns transmit permits based on the service tag values and the available data slots. If a packet is lost or in error, the sending remote recomputes the service tag values of all its queued packets, including the packet whose transmission failed. Alternatively, the remote informs the base station of its queue size and the base station computes service tags for each remote based on the service shares of the remote and the available data slots. If a packet is lost or in error, the base station recomputes the service tag values for that remote host based on the current system virtual time. In an alternate embodiment, the a or wireless node maintains a packet queue and a head-of-line tag. If a packet is lost, only the head-of-line tag needs to be changed. Once the head-of-line packet has been transmitted successfully, the rest of the queued packets will automatically receive the correct tag, the recomputed head-of-line tag plus appropriate increments. For half-duplex, both the uplink and downlink queues at the access points are managed as if there is only one system virtual time. For full-duplex, separate system virtual times for the uplink and the downlink traffic may be used. Remotes may also be divided into one or more separate groups, with each group having a different priority and receiving a different system virtual time. Service tags of all other remotes remain unaffected by the retransmission of a packet from any particular remote, meaning that the QoS experienced by the other remotes does not suffer.

Title: Heat shield with moldable insulation
Inventor: DUTCHER DALE E
IPC: G01K1/14
Filed: 1998-10-14
Granted: 2008-06-17
Abstract: A temperature monitoring assembly adapted to be positioned adjacent a structure in order to make temperature measurements at the surface of the structure is provided. The assembly includes a thermocouple means, a pad adapted for weldable attachment to the surface of the structure and having a slot therein for securing an end of the thermocouple means adjacent the surface of the structure at a desired location, and a heat shield forming a partially enclosed volume and having an opening shaped to conform to the surface of the structure so as to protect the thermocouple means from radiated heat when the shield is placed upon and welded to the structure over the thermocouple means. A portion of the thermocouple means extends though a slot in the heat shield to communicate measured temperature data. Insulating material is positioned within the partially enclosed volume of the heat shield for thermally isolating the thermocouple means so that the thermocouple means is substantially exposed only to heat transferred from the structure. The insulating material is moldable to the shape of the pad and the thermocouple means and hardens to a semi-rigid form, whereby premolding of the insulating material within the heat shield ensures that the heat shield will be properly placed over the pad and the thermocouple means for accurate temperature measurement of the structure.

Title: Means and methods for the treatment of neurological disorders
Inventor: FISCHELL ROBERT E
IPC: A61N1/32
Filed: 1998-10-26
Granted: 2012-12-18
Abstract: Disclosed is a multiple electrode, closed-loop, responsive system for the treatment of certain neurological diseases such as epilepsy, migraine headaches and Parkinson's disease. Brain electrodes would be placed in close proximity to the brain or deep within brain tissue. When a neurological event such as the onset of an epileptic seizure occurs, EEG signals from the electrodes are processed by signal conditioning means in a control module that can be placed beneath the patient's scalp, within the patient's chest, or situated externally on the patient. Neurological event detection means in the control module will then cause a response to be generated for stopping the neurological event. The response could be an electrical signal to brain electrodes or to electrodes located remotely in the patient's body. The response could also be the release of medication or the application of a sensory input such as sound, light or mechanical vibration or electrical stimulation of the skin. The response to the neurological event can originate from devices either internal or external to the patient. The system also has the capability for multi-channel recording of EEG related signals that occur both before and after the detection of a neurological event. Programmability of many different operating parameters of the system by means of external equipment provides adaptability for treating patients who manifest different symptoms and who respond differently to the response generated by the system.

Abstract: Disclosed is a Faraday rotator capable of reducing the temperature dependence on a Faraday rotation angle, thereby enhancing the temperature characteristic, particularly, in a service environment in which the magnetization direction is variable, and an optical device using the Faraday rotator. The Faraday rotator includes a Faraday element which rotates the polarization plane of polarized light rays passing through the Faraday element when an external magnetic field is applied to the Faraday element. In this Faraday rotator, assuming that an angle between a magnetization direction of the Faraday element and a light ray direction is taken as .alpha., the amount of the temperature-dependent change in Faraday rotation angle is reduced by applying the external magnetic field in a direction in which a first amount of the change in Faraday rotation angle due to the temperature dependence on the angle .alpha. and a second amount of the change in Faraday rotation angle due to the temperature dependence on the Faraday effect satisfy a relationship in which the sign of the first amount is plus or minus, the sign of the second amount is minus or plus, and the absolute value of one of the first and second amounts is less than twice the absolute value of the other amount, more preferably, substantially equal to the absolute value of the other amount.

Abstract: In a system with a range of dental screws (2), the screws are tightened by means of one and the same screw tightener (1). The screws are of different types and have different constructions. Each screw has an internal recess (4) via which the cooperation with the screw tightener is afforded. Each recess has elements extending inwards towards the centre axis of the screw, and the screw tightener has parts which can cooperate with the elements. The bearing capacity function is effected by the conicity of the said parts, while the driving function between tightener and screw is effected by means of axially extending elements and parts. The driving and the bearing capacity are in this case mechanically separated.      The invention may also be seen as a range of dental screws.

Abstract: L'invention concerne un appareil et un procédé destinés à un système de communication équipé d'un émetteur (2) et d'un récepteur (4). Le récepteur détermine à quel débit parmi plusieurs débits l'émetteur a transmis des trames individuelles d'un signal. Par exemple, si l'émetteur (2) utilise quatre débits de transmission, le récepteur (4) décode chaque trame du signal reçu en fonction des quatre débits pour produire quatre bits de contrôle de redondance cyclique (CRC), quatre valeurs de débits d'erreur de symbole (SER) et une ou plusieurs valeurs de contrôle de Yamamoto. Si seuls deux des bits CRC se vérifient, le récepteur (4) compare l'une avec l'autre les valeurs SER pour ces deux débits pour déterminer lequel des deux débits a été utilisé pour transmettre une trame ponctuelle. Si seul un des bits CRC se vérifie pour un débit donné, la valeur SER pour ce débit est comparée avec un seuil SER maximal pour ledit débit. De plus, des valeurs SER pour les autres débits peuvent être comparées avec des seuils SER minimaux. Par ailleurs, les valeurs de contrôle de Yamamoto peuvent être analysées pour déterminer s'il conviendrait d'utiliser des seuils SER minimaux ou maximaux plus larges ou plus resserrés dans le cas où les valeurs de contrôle de Yamamoto se vérifient pour le débit ponctuel ou ne se vérifient pas, respectivement.

Abstract: Dans les systèmes de télécommunication à commutation par paquets en mode connecté connus, les ressources de la voie de transmission entre le noeud de service (SGSN) et le sous-système du réseau de radiocommunication (RNS) sont réservées inutilement en raison de la nature des paquet de données, dont l'émission se fait par rafales. Ceci entraîne l'utilisation de l'espace adresse limité du réseau de transmission et des ressources de gestion du sous-système du réseau de radiocommunication. L'invention concerne un procédé de gestion de connexion dans un système de radiocommunication mobile qui convient pour la transmission à commutation par paquets. Ce procédé est caractérisé en ce que la connexion logique entre le noeud de service (SGSN) et le sous-système du réseau radio (RNS) est libérée de manière que la connexion logique entre le noeud de service (SGSN) et la station mobile (MS) est maintenue, et la connexion logique libérée est reconnectée lorsque la transmission des données utilisateur démarre.
