| 20110226251 | Respirator Mask for a Compressed Air Breathing Apparatus - The invention relates to a respiratory protection mask for a compressed air breathing apparatus comprising a pulmonary machine which is controlled by a control membrane when the wearer of the mask breathes in. According to the invention, the air outlet of the expiratory valve and the control membrane are covered by a common cover, forming a rinsing area on the outside of the control membrane through which homogeneously temperate, clean rinsing air flows from the air outlet to the air discharge openings in the cover, thereby ensuring high functionality and high service life of the membrane-controlled pulmonary machine despite extreme environmental conditions. | 09-22-2011 |
| 20110098921 | Navigational System Initialization System, Process, and Arrangement - An initialization system for a personal navigation system associated with a user, including: a first reference point arrangement configured for communication with the personal navigation system of the user and to facilitate the generation of a first user data set including horizontal position and azimuth angle (x | 04-28-2011 |
| 20110072547 | Protective Headwear - A helmet includes a shell having a lower edge, and an edge support extending around the lower edge of the shell. The edge support has a greater structural rigidity than the shell. The helmet can further include a retention strap system, and the edge support can include at least one attachment to attach the retention strap system to the helmet. The attachment can, for example, include a seating, and the helmet can, for example, further include an abutment member removably seatable within the seating. The abutment member can be attachable to a strap of the retention strap system. | 03-31-2011 |
| 20110061522 | BALLISTIC PANEL ASSEMBLIES FOR USE IN BODY ARMOR AND METHOD OF FORMING BALLISTIC PANEL ASSEMBLIES - A ballistic panel assembly for use in body armor includes at least one subassembly including at least one layer including fibers that extend from at least one side thereof and at least one edge guard encompassing at least a portion of the extending fibers. The ballistic panel assembly further includes a waterproof cover encasing the at least one subassembly. The cover includes a front section and a rear section. A waterproof seal is formed between the front section and the rear section around at least a portion of perimeters thereof adjacent to the at least one edge guard after the subassembly is placed between the front section and the rear section. The edge guard can, for example, include an adhesive tape. | 03-17-2011 |
| 20110029241 | Personal Navigation System and Associated Methods - A personal navigation system, including: at least one inertial sensor module associated with a user, the inertial sensor module comprising at least one sensor to generate location data associated with the user; a communication device to receive and/or transmit at least a portion of the location data; and an onsite computer to communicate with the communication device and receive at least a portion of the location data; wherein at least one of the inertial sensor module and the onsite computer is configured to determine at least one activity of the user based at least in part upon the location data; wherein the onsite computer is programmed to configure a display including a representation of the user based at least in part upon the location data; wherein at least one of the determination and the configuration is performed substantially in real-time. | 02-03-2011 |
| 20100294590 | Method, Apparatus, and Arrangement for a Lifeline System - A shuttle member for a horizontal lifeline system having at least one elongate line attached between at least two anchorage points. The shuttle member includes: a body having: (i) an upper portion configured for attachment to the line by at least partially surrounding the line; (i) an intermediate portion that, together with the upper portion, defines at least one passage slit that is sized such that the elongate line cannot pass therethrough; and (iii) an attachment portion configured for attachment of at least a portion of a lanyard. A shuttle member arrangement and a passing method are also disclosed. | 11-25-2010 |
| 20100007485 | Devices, Systems and Method of Determining the Location of Mobile Personnel - A locator system for use in connection with at least one mobile person includes a mobile locator system adapted to be worn by the person, wherein the mobile locator system includes an inertial navigation system. The locator system further includes a reference locator system to provide information about a position of the mobile locator device relative to a coordinate system. In several embodiments, the reference locator system comprises an ultrasonic system. For example, the reference locator system can include at least one ultrasonic transmitter and at least one ultrasonic receiver. One of the at least one ultrasonic receiver and the at least one ultrasonic transmitter can be positioned at a known position on the coordinate system and the other of the at least one ultrasonic receiver and the at least one ultrasonic transmitter can be worn by the person. The reference locator system can also include a plurality of ultrasonic transmitters and a plurality of ultrasonic receivers. Each of the plurality of ultrasonic receivers or each of the plurality of ultrasonic transmitters can be positioned at known positions on the coordinate system. Each of the other of the plurality of ultrasonic receivers and the plurality of ultrasonic transmitters can be worn by one of a plurality of persons. | 01-14-2010 |
