Abstract: Electronic stroke indicators have sensor structures (34, 60, 80, 110) which are incorporated into a stone shield (28, 62, 82, 116) for a brake actuator (20). The incorporation of the sensor (34, 66, 119) stone shield (28, 62, 116) protects the sensor (34, 60, 119) and its associated wires (50, 69, 121) and contacts from damage by the other components in the brake actuator (20). In particular, the spring is typically maintained out of contact with any of the electric portions of the electronic stroke indicator, thus prolonging the life of the electronic stroke indicator. In further features of this invention, a magnetic sensor (34) may monitor the position of magnetic portions (36) on a piston rod (32). Alternatively, a pair of electric contact switches (96, 98) may be serially contacted by a structure on the piston rod (94) as the broke moves further out of stroke. The two electric contacts (96, 98) provide different signals to an operator in a vehicle cab such that signals of the level of out-of-stroke conditions are provided to the operator. In a further embodiment, a load cell (119) monitors the compression in a spring (112) in the brake housing (111) to provide an indication of an out-of-stroke condition.
Patent CA-2523676-A1 (CA)
Title: Dna vaccine expressing ha1 of equine-2 influenza virus
Inventor: LAI ALEXANDER
IPC: C07K14/11
Filed: 2004-04-16
Abstract: The invention is for a DNA vaccine expressing the hemagglutinin (HA1) gene of equine-2 influenza virus. By engineering a stop codon within HA1, expression of HA1 is ensured. By encapsulation of the DNA vaccine in liposome and by intranasal inoculation, it is sufficient to elicit protective immunity at a significantly lower dosage compared to a DNA vaccine expressing the full length HA gene. Lower dosage reduces the risk of induction of anti-DNA  antibodies. Intranasal inoculation directly to the respiratory epithelial cells reduces the risk of DNA integration. The inventive vaccine is advantageous over current inactivated or live attenuated vaccines, as updating of the vaccine requires only the replacement of the encoding sequence with the new virus.
