Patent CA-2209944-A1 (CA)
Inventor: H M L INEN JARI
IPC: H04L12/56
Filed: 1996-01-08
Abstract: Système radio permettant d'encapsuler des paquets de données de réseaux de données externes selon un protocole de point à point PPP (fig. 4A, 4B) et de les transmettre par l'intermédiaire d'un ou plusieurs sous-réseaux vers un point qui utilise le protocole du paquet encapsulé. En outre, un protocole de liaison radio spécial (SRLP) du réseau radio de transmission de paquets doit être appliqué à l'interface radio reliant un équipement terminal de données mobiles et un noeud de prise en charge. Les paquets PPP sont encapsulés en paquets de données SRLP. L'inconvénient est que les paquets de données PPP et SRLP contiennent des  champs de contrôle spécifiques au protocole, ce qui réduit la capacité de transmission de l'information d'usager. Par conséquent, on comprime un paquet PPP (fig. 4C) avant l'encapsulation (fig. 4D) en le dépouillant des champs de commandes non nécessaires. Après transfert sur l'interface radio, le paquet PPP est décomprimé et reprend son format d'origine (fig. 4F, 4G).

Patent CA-2234978-A1 (CA)
Inventor: JACOBSON ROBERT D
IPC: F15B13/01
Filed: 1998-04-17
Abstract: In order to achieve repeatable, consistent operation of a counterbalance valve, a poppet valve element within the valve has a radial bore therein in communication with a control fluid port an an axial bore therein which receives a rod that is anchored to a poppet valve cage that surrounds the poppet valve element.  The poppet valve element is urged by a spring into engagement with a valve seat and pilot pressure is applied in opposition to the spring.  By virtue of this arrangement, control fluid pressure is applied via the rod directly to the valve body in which the poppet valve element and cage are mounted.  By changing the diameter of the rod and axial bore through the poppet valve element which receives the rod, the relief set pressure can easily be changed.

The output signal is time averaged (14) and provided to a comparator circuit (21). A predetermined threshold signal (28 OR 32) is also provided to the comparator circuit (21), and the two signals are compared. An AC-to-DC converter (38) or power supply is coupled to the utility's electric line (L1, L2, L3, AND N) and provides a DC voltage on its ouput. The amplitude of the DC voltage is controlled by the output signal from the comparator circuit (21). A power isolation and ditribution circuit (48) and a storage battery (34) are also included. The power isolation and distribution circuit is connected between the AC-to-DC converter (38) and the storage battery (34). The power management system senses peak power demands for electricity, and switches a particular load (46) of the customer from being powered by the AC-to-DC converter (38) to the storage battery (34). When there is no peak power demand, the AC-to-DC converter (38) powers the particular load (46).
