Granted: 2000-01-25
Abstract: A hand held actuator comprises a truncated conical housing wherein the volume of air is pressurized by flexure of a diaphragm. A rib protruding from an outer peripheral margin of the diaphragm is received in a groove of a support plate.      Unwanted flexure of the peripheral margin is prevented by supporting the edges supporting the edges of the diaphragm and the plate is spaced apart grooves formed in the interior wall of the housing. The volume of air pressurized by the operation of the diaphragm is communicated by a duct to a signal switch. In one embodiment the duct is connected in a fluid type manner to the interior of the housing by the tapered sleeve. In another embodiment, the duct is joined to a tube forming an extension in an opening in the support plate forming a diaphragm.

Title: Sonet ring subnetwork management method
Inventor: LU TSU-KAI
IPC: H04B10/275
Filed: 1994-06-29
Granted: 1998-10-13
Abstract: ABSTRACT OF THE DISCLOSURE    A method of managing a telecommunication subnetwork system composed of a number of network elements coupled together through an optical medium to form a Synchronous Optical NETwork (SONET) ring.  Each of the network elements receives upon initiation or reconfiguration and then stores an identical  ring table or knowledge database that is composed of data in a predetermined format and structure.  The ring table defines the ring type and ring  identification,  number  of  nodes,  ring  status,  node identification,  sequence,  and  status,  and  provides  ring provisioning   tables   and   embedded   SONET   ring   path identification/status information.  The ring table is utilized in each of the network elements for provisioning and other management type functions common within a SONET ring environment.

Abstract: Un procédé d'analyse des caractéristiques propres à un réseau de télécommunications par la mesure des propriétés vocales transitant par la ligne contrôlée, consiste à identifier une partie du signal vocal possédant une propriété indépendante du locuteur, et à détecter dans le signal reçu, les écarts par rapport à cette propriété, puis à identifier en conséquence des caractéristiques du signal qui sont imposées par le système. Les propriétés identifiées peuvent être des formes d'ondes caractéristiques de phonèmes prononcés, et le fait que la voix humaine ne peut émettre que certains sons permet de déterminer quel écarts ont été imposés à ces sons par le système. Dans une variante, on identifie une partie du signal vocal, qui varie de façon prédéterminée par rapport à une caracteristique absolue du locuteur, et on en dérive des caractéristiques absolues. Une telle caractéristique absolue peut être le niveau absolue de la voix, et l'autre propriété peut être une fonction, indépendante du locuteur, relative à ce niveau absolu, telle que la teneur spectrale des consonnes fricatives n'impliquant pas la voix.

Abstract: The contact lens applicator is for use in inserting a contact lens into a person's eye, and comprises an elongate member, securing means for securing the applicator to the finger of the person, and a contact lens retaining means. In use the contact lens applicator is secured on the finger of the person adjacent the fingertip by the securing means and a contact lens is placed on the contact lens retaining means. The contact lens is oriented on the contact lens retaining means such that the inner concave portion faces away from the contact lens retaining means. The contact lens retaining means holds the contact lens in place with sufficient force such that the contact lens is held on the applicator when the applicator is moved into a position with the finger substantially horizontal and with the contact lens extending forward of the fingertip. This allows the contact lens to be inserted into the eye easily and without tilting the head downwards, and enables a person to hold both the top and bottom eyelids open with the fingers of both hands. The contact lens is inserted into the eye by moving the applicator towards the eye until the lens lightly touches the eye which releases the lens.
