Title: Railway indicator device and method
Inventor: LAFRENIERE RENE G
IPC: E01F9/60
Filed: 2004-05-03
Granted: 2012-09-18
Abstract: A railway indicator device is provided for indicating a condition associated with a particular section of track of a railway. The device includes a post supported in the ground adjacent the railway track which pivotally supports a swing arm thereon for movement between a raised position extending vertically above the post and a lowered position extending horizontally across the railway track spaced above the ground. An indicator panel, for example a blue flag indicator is supported on the free end of the swing arm for pivotal movement therewith relative to the post. The pivoting swing arm permits the indicator panel to be readily retracted or deployed by a single operator while minimizing opportunity for the indicator panel to be lost or damaged as commonly occurs with conventional designs of indicators used on railways.

Abstract: Methods and apparatus for facilitating concurrent Push-to-talk over Cellular (PoC) group communication sessions for a mobile station are disclosed. A first PoC communication session for a first user group is maintained while a second PoC communication session for a second user group is concurrently maintained, where the second user group has at least one common member with the first user group. The second user group may have at least one member which is not included in the first user group. Through a user interface, a PoC user may select between the first and the second user groups for communication or combine the communications. In an alternative embodiment, all of the members of a second user group may be included in a first user group. In a specific approach, encrypted data packets of a PoC communication sub-session are communicated during a PoC communication session. If a key for the encrypted data packets is known for the mobile station, the encrypted data packets are decrypted to facilitate the PoC communication sub-session involving the mobile station; otherwise the encrypted data packets are discarded.

Title: Apparatus and method for distributing buffer status information in a switching fabric
Inventor: JACOBS MICK R
IPC: G06F13/40
Filed: 2003-11-05
Granted: 2010-08-10
Abstract: Network switching and/or routing devices can use switching fabrics that gather information about output port buffer status and distribute that information to various line cards for use in data frame congestion avoidance. The switching fabric can gather output buffer status information for all output ports and distribute that information to each line card in an efficient, in-band manner.  Individual line cards can use the information to determine from which line card virtual output queue to dequeue data frames destined for the switching fabric. Line cards can also gather output buffer status information associated with line card queues used for receiving data from the switching fabric. Such data is used in a manner similar to the output buffer data from the switching fabric.

Abstract: An apparatus and methods are disclosed for enabling a telecommunications terminal to notify its user of the arrival of a message via an acoustic or visual signal whose properties are based on attributes of the message. A network infrastructure element (e.g., a switch, a private branch exchange [PBX], a server, etc.) receives a message directed to a terminal and sets the values of ringtone properties (e.g., tempo, volume, pitch, rhythm, etc.) based on attributes of an incoming message (e.g., the sender, a priority, a subject, the location from which the message was sent, etc.). In a first illustrative embodiment the network infrastructure element sends the message and the instantiated ringtone to the terminal, while in a second illustrative embodiment the network infrastructure element sends the message and the property values to the terminal, and the terminal plays a locally-stored ringtone in accordance with the property values.

Title: Automatic corral gate closure
Inventor: LENZ DON
IPC: E05F1/14
Filed: 2005-07-29
Granted: 2010-10-26
Abstract: A ranch gate arm assembly which incorporates a gate arm that is mounted to allow swiveling about a longitudinal pivot when an external man or machine force is applied to either side of the gate arm thereby inducing the gate arm to swing out, and two torsion springs, one assembled on each side of the ranch gate arm which push against correlating sides of the gate and push the gate back to a centre position after the external force has passed completely through the opening.  This gate arm assembly is equipped with a smoothing release assembly, which eliminates the jolt force caused by the quick returning of the gate assembly to the centre position that the gate was originally in before the external force was applied.

Granted: 2011-08-23
Abstract: The invention describes compounds, compositions and methods of using the same comprising a chemical moiety covalently attached to amphetamine. These compounds and compositions are useful for reducing or preventing abuse and overdose of amphetamine. These compounds and compositions find particular use in providing an abuse-resistant alternative treatment for certain disorders, such as attention deficit hyperactivity disorder (ADHD), ADD, narcolepsy, and obesity. Oral bioavailability of amphetamine is maintained at therapeutically useful doses. At higher doses bioavailability is substantially reduced, thereby providing a method of reducing oral abuse liability. Further, compounds and compositions of the invention decrease the bioavailability of amphetamine by parenteral routes, such as intravenous or intranasal administration, further limiting their abuse liability.

Abstract: Afin d'examiner un degré de diplopie monoculaire facilement et de manière quantitative, le patient observe d'un seul oeil plusieurs repères oculaires circulaires à partir une distance d'examen prédéterminée dans le but de trouver un repère particulier par lequel les images doubles observées se touchent. On détermine le degré de diplopie monoculaire à l'aide de l'angle de vision se rapportant au repère oculaire circulaire d'intérêt. Puisque le repère oculaire est de forme circulaire, on peut examiner le degré de diplopie monoculaire indépendamment de la direction axiale le long de laquelle les images doubles apparaissent.
