20080198003 | Marine Personal Locator Apparatus - Marine personal locator system including personal transmitters activated by immersion and a receiver. The transmitter includes a microprocessor adapted to effect transmission of a unique tone identifying the transmitter. The receiver includes an omnidirectional and a yagi antenna switchable to a tuned RF amplifier, mixed with a frequency doubled crystal oscillator local oscillator signal, filtering, processing to retrieve any unique identifying tone, and signal strength detection and indication means. The transmitters are worn by sailors and the receiver is located on a vessel. The receiver is operable to monitor for any signals of a transmitter worn by a sailor fallen overboard using the omnidirectional antenna and sound a siren in the event of reception of such a signal. A sailor operating the receiver can switch to use the yagi antenna and using the signal strength indication means determine and monitor the direction of an overboard sailor relative to the vessel. | 08-21-2008 |

20120266357 | REINFORCING ELEMENT FOR A GLOVE, AND GLOVE, IN PARTICULAR A GOALKEEPER'S GLOVE HAVING SUCH A REINFORCING ELEMENT - The invention relates to a reinforcement element for a glove, especially for a goal keeper's glove, which is designed to allow a bending in a first bending direction and to prevent a bending in a second bending direction which is contrariwise to the first bending direction. To prevent reliably that the joints of the fingers are subjected to high forces during fisting of a ball, the invention is characterized in that the reinforcement element comprises two bending elements which extend in a longitudinal direction of a finger, which bending elements comprise a number of blocking elements for the prevention of a bending in the second bending direction, wherein the two bending elements run during regular use laterally beside the finger which is to be protected, wherein the two bending elements are connected to another by at least two connecting bridges. Furthermore, the invention relates to a glove, especially to a goal keeper's glove with such a reinforcing element. | 10-25-2012 |
