Abstract: Armor, in particular body armor for female wearers is made of multiple layers (30) of penetration-resistant material for example made of polyaramid fibers, specially shaped to fit over a shaped area to be protected, e.g., the bust of a female wearer. The armor's shaped part is held in shape by a series of darts (37) in successive layers (30) of the material. Each dart in a material layer comprises a generally V-shaped section (35) whose edges (37) are joined to form the dart. The V-shaped section (35) of the material is folded on itself to form a pleat (40) which is folded over to one side of the dart (37) to form an added thickness overlaying or underlying an adjacent part of the material (30). The darts (37) are angularly offset from one another with the pleats (40) oriented in directions so that the added thickness is distributed substantially evenly, thereby avoiding bulges or stiffness and improving the wearing comfort. Preferably, the layers of material are fabric covered over selected areas thereof to be protected with a bonded or coated reinforcing film, except in the folded V-shaped sections.

Inventor: FORSSELL MIKA
IPC: H04W52/02
Filed: 1999-11-26
Abstract: The invention relates generally to a method and an arrangement for transferring information in a packet radio service.      Especially the invention applies to transferring delay sensitive data, such as speech and video data, in a mobile telecommunications system. It is an object of this invention to provide a solution, in which the physical connection of a packet radio service is kept reserved also during the passive periods of a session but the same physical resource can still be shared between multiple users. A basic idea of the invention is that the network is informed at the end of an active period, on whether a passive period follows the active period or if the connection can be released. When an active period starts after a passive period, the connection preferably reserves the packet data channel again, and possible other users of the channel are assigned to other channels.

Title: Method and apparatus for controlling received power levels within a free-space optical communication system
Inventor: PRESBY HERMAN MELVIN
IPC: H04B10/118
Filed: 2001-09-28
Abstract: A free space optical communication system is disclosed whereby the received power at the receive optical fiber is reduced by adjusting the transmitted light beam and the receive optical fiber with respect to each other when a specified power threshold is exceeded so that they intersect not at a point of focus, but at a point of divergence of the transmitted beam. In one embodiment, the transmitted beam may be diverged by moving the transmit optical fiber to a point in front of the focal plane of the transmit telescope along the longitudinal axis of that telescope until at least a portion of the beam is incident upon the receive optical fiber. This causes the transmitted beam to diverge and, accordingly, the cross-sectional area to increase at the point where it is incident upon the receive telescope. As a result, the cross-sectional power per unit area of the transmitted beam at the receive telescope is reduced which correspondingly reduces the power that is incident upon the receive optical fiber.        In another embodiment, instead of moving the optical fiber at the transmit telescope, the optical fiber located at the focal plane of the receive telescope may be moved to either a point in front of or to a point to the rear of the focal plane of the receive telescope along the longitudinal axis of the receive telescope. Since the maximum possible received power is achieved at the focal point within the focal plane, any movement of the receive optical fiber away from the focal point along the longitudinal axis of the receive telescope will result in a reduction of the received power.
