Abstract: Dynamic parameter tuning using particle swarm optimization is disclosed. According to one embodiment, a system for dynamically tuning parameters comprising a control unit; and a system for receiving parameters tuned by the control unit. The control unit receives as input a model selection and definitions, and dynamically tunes a value for each parameter by using a modified particle swarm optimization method. The modified particle swarm optimization method comprises moving particle locations based on a particle's inertia, experience, global knowledge, and a tuning factor. The control unit outputs the dynamically tuned value for each parameter.

Abstract: A tool head suitable for use in a machine tool for shaping the edge of a plastic sheet, which holds and shapes the edge of plastic sheet while a vacuum on the machine tool holds the center of the plastic sheet. Having such a desired edge renders the plastic sheet suitable for further manufacturing treatment.

Abstract: A concealed magazine slot arrangement includes a magazine holder, a gear carrier, and a fastening device for fastening the magazine holder on the user's body. The magazine holder includes an inner panel, an outer panel, having a front operation side, overlapped thereon, and a plurality of slot dividers affixed between the inner and outer panels to form a plurality of magazine slots concealed within the inner panel, the outer panel, and the slot dividers for receiving the magazine. A gear carrier is provided on the front operation side of the magazine holder for carrying a gear thereon. Quick accessing fasteners facilitate securing magazines in magazine slots. Means for adjusting the depth of the magazine slots are provided.

Abstract: A carrying bag comprising a main compartment having a front panel, a back panel and two side panels; two side flaps attached to the back panel protruding laterally; and a carrying strap having a first end attached to the first side flap and a second end attached to the second side flap, wherein the first and second side flaps have a first configuration and a second configuration, wherein in the first configuration, the side flaps project upwards so that the carrying strap can function as a shoulder strap and in the second configuration, the side flaps can be folded and secured onto itself to project laterally and function as a waist strap.

Abstract: A weapon support pad comprising a pad comprising a fastening mechanism to attach to the forend of a weapon, such as a rifle to provide support and absorb unwanted vibrations, among other advantages. The pad may be quickly and easily attachable and detachable from the weapon. A variety of fastening mechanisms may be utilized, including the hook-and-loop.

Abstract: The present invention discloses an interlock attaching strap system, comprising a carrier having a plurality of first webbing strips transversely, evenly and spacedly affixed thereon, a holder having a plurality of second webbing strips transversely, evenly and spacedly affixed thereon, wherein by overlapping the carrier and holder, the first webbing strips and the second webbing strips are capable forming an elongate interlocking channel; at least an elongated interfering strap, which is longitudinally extended on the holder, having an affixing end extended from a peripheral edge of the holder and a free tab end, arranged to slidably pass through the interlocking channel and is hooked onto the last webbing strip so as to securely reinforce the holder on the carrier via the interfering strap.

Abstract: In a cooling device for cooling an object to be cooled without using a forced cold air circulating system, which circulates cold air forcibly, a cooling device at a practical level is provided, and a cooling device capable of achieving a sufficient cooling effect is provided. A cooler 18 is provided in an interior that is insulated adiabatically from an exterior, a cooling fan 20 is disposed on a front surface of the cooler 18, a cooling chamber 22 in which an object to be cooled is placed is defined by a space in front of the cooling fan 20, a cooled air behind the cooling fan 20 is drawn with the fan and allowed to flow into the cooling chamber 22, and a/D=½ to ¼ is satisfied, where a indicates a dimension of a gap between the cooler 18 and the cooling fan 20 along a front-back direction and D indicates a diameter of the cooling fan 20.

Abstract: A cooling device of the present invention, includes: a cooler provided on at least one side-wall side of a chamber formed with a thermal insulating box; a cooling chamber in front of the cooler; and a fan that allows air in the cooling chamber to flow. The cooler and the cooling chamber are partitioned by a partition so as to allow cold air to be accumulated in the cooler, the fan is disposed on a side of the cooler relative to the partition, the partition in front of the fan has an aperture, and cold air accumulated in a space inside the partition and hot air in the cooling chamber are exchanged by the fan through the aperture. Thereby, a cooling device with a simple configuration and excellent cooling performance can be provided, by which the amount of frost deposited on a cooling coil can be reduced and the miniaturization of the device can be realized.
