Patent number: 11184981Abstract: A rigid-flex PCB includes an array of rigid PCB “islands” interconnected by a flexible PCB formed into flexible connectors. The conductive and insulating layers of the flexible PCB extend into the rigid PCBs, giving the electrical connections to the rigid PCBs added resistance to breakage as the rigid-flex PCB is repeatedly stressed by bending and twisting forces. In addition, the durability of the rigid-flex PCB is enhanced by making the power and signal lines driving the rigid PCBs redundant so that a breakage of a line will not necessarily affect the operation of the rigid PCB to which it is attached. The rigid-flex PCB is particularly applicable to light pads used in phototherapy, wherein LEDs mounted on the rigid-PCBs are powered and controlled through the redundant lines in the flexible PCB.Type: GrantFiled: August 5, 2018Date of Patent: November 23, 2021Assignee: Adventive IP BankInventors: Richard K Williams, Keng Hung Lin

Patent number: 7464793Abstract: An emergency power operation apparatus of an elevator that operate machines in a firefighter operation according to the situation in a case where a power failure occurs during firefighter operations during a fire and a switchover to an emergency power source occurs. A group-management controller causes machines not in firefighter operation to preferentially return to an evacuation floor or a rescue floor when a power failure occurs during firefighter operations during a fire and then makes machines in firefighter operation operational. In a case where there are multiple machines in firefighter operation after all machines not in firefighter operation have finished returning to an evacuation floor or a rescue floor, if there is a machine at a standstill outside a door zone among the machines in firefighter operation, the group-management controller causes that machine at a standstill outside the door zone to preferentially become operational.Type: GrantFiled: June 24, 2004Date of Patent: December 16, 2008Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Masashi Komatsu

Publication number: 20080289907Abstract: The invention relates to a method and an apparatus for controlling advance opening of doors in a double-deck elevator, in which elevator a car frame (2) supporting the elevator cars (1a and 1b) is moved by means of a set of hoisting ropes (3) by a hoisting machine (46) provided with a traction sheave. When the elevator is approaching the target floor levels (51, 52), the velocity of the elevator cars (1a and 1b) in the car frame (2) in relation to the car frame (2) is measured and, based on the measurement result, the velocity of the elevator cars (1a and 1b) relative to the floor levels (51, 52) is calculated.Type: ApplicationFiled: June 10, 2008Publication date: November 27, 2008Applicant: KONE CORPORATIONInventor: Risto Kontturi

Publication number: 20080271955Abstract: An elevator door lock assembly (30) includes a sensor device (40) for providing an indication of a properly locked door. A plurality of proximity sensor elements (42, 44) interact with activating elements (52, 54) when the door lock assembly (30) is properly locked. In disclosed examples, a specific geometric pattern of the sensor elements (42, 44) and the activating elements (52, 54) provides redundancy and tampering protection. In a disclosed example, an output from the sensor device (40) provides an indication of a condition of the door lock and a building level location of a plurality of sensor devices.Type: ApplicationFiled: September 27, 2004Publication date: November 6, 2008Inventors: Muhidin A.

Patent number: 7413059Abstract: In a fire control system for an elevator, the time for the fire and smoke to reach the elevator hall of each floor of a building during fire is pre-calculated as the evacuation time of the floor. When the evacuation time of a floor is longer than the time for making a car respond to a rescue call from the evacuation floor, the floor is judged as a rescue floor, and when shorter, the floor is judged as a non-rescue floor. Furthermore, the order in which the rescue is carried out among the rescue floors is determined. Accordingly, it is possible to rescue remainders on a rescue floor using an elevator as an evacuation means. Moreover, since rescue operation by the elevator is performed with the order of rescue determined, rescue operation suitable for the conditions of the fire can be realized.Type: GrantFiled: March 20, 2007Date of Patent: August 19, 2008Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Kiyoji Kawai

Patent number: 7353914Abstract: A safety system for an elevator installation for the transport of persons/goods in a building and a method for operating an elevator installation with a safety system. Several cages are moved one above the other in a shaft. Each cage is moved by a drive. At least one drive control controls the drives by way of drive control signals. Cage position detecting sensors detect positions of each cage and transmit cage position data to at least one safety control. Access to the shaft takes place by way of opened shaft doors. A lock locks the shaft doors. Lock setting detecting sensors detect settings of the locks of the shaft doors and transmit lock setting data by way of the data bus to the safety control. The safety control ascertains, from the cage position data and the lock setting data, shaft region data with details with respect to shaft regions in which each cage is safely movable.Type: GrantFiled: September 29, 2004Date of Patent: April 8, 2008Assignee: Inventio AGInventor: Romeo Deplazes

Publication number: 20080078626Abstract: In an elevator system that has an elevator hoistway, a plurality of hoistway doors arranged above each other each with at least one horizontally moveable hoistway door panel, and an elevator car with a car door that has at least one horizontally movable car door panel, fastened to the car door panel is a vertically extending barrier rail. In each of the areas lying in the vertical direction between the hoistway door panels of adjacent hoistway doors two locationally fixed stopping dogs that are vertically spaced from each other are arranged so that in each case one of the stopping dogs limits the opening movement of the barrier rail, and thereby of the car door panel, when the position of the elevator car deviates in the upward direction or in the downward direction by a certain minimum distance from the intended stopping position.Type: ApplicationFiled: September 28, 2007Publication date: April 3, 2008Inventor: Hans Kocher

Patent number: 7316297Abstract: Provided is an elevator escape device. In response to a stop of the elevator due to power outage, a trapped person may press a switch to activate a backup generator, and either a backup electromagnetic contact is enabled if the backup generator functions normally or the person manipulates a handle to activate a slow movement assembly if the backup generator malfunctions. Thereafter, the brake is disabled by contacting a first detent a return assembly operates to return a slow movement assembly to its nonoperating position via a control assembly wherein electromagnetic contacts are short-circuited sequentially by contacting corresponding electromagnetic contacts, the car slowly arrives at a nearest correct floor, and the trapped person may to open a door to escape.Type: GrantFiled: May 27, 2005Date of Patent: January 8, 2008Inventor: Chiu Nan Wang

Patent number: 7270218Abstract: A device moves a door seal for a displaceable door panel of an elevator car in an elevator installation with an elevator shaft having shaft doors. The movable door seal is arranged so that the door panel in a closed state is sealed off. The device includes an entrainer unit connected with the door panel and upon stopping of the elevator car at a floor executes a part movement. The device also includes a coupling mechanism mechanically connecting the entrainer unit with the door seal to bring the door seal out of a sealing position into an open position when the entrainer unit executes the part movement.Type: GrantFiled: April 20, 2004Date of Patent: September 18, 2007Assignee: Inventio AGInventors: Peter J. Spiess, Dario Augugliaro
