Abstract:
A personal flight device which includes a housing which is securable to a pilot having at least one pair of ducted fans, one fan of the at least one pair of ducted fans is mounted to one side of the housing, the other fan of the at least one pair of ducted fans mounted to the other side of the housing. Each fan rotates about an axis of rotation so as to draw air through the corresponding duct from an entry end of the duct to an exit end of the duct. At least one radiator is also provided. Each engine of the at least one engine is cooled by a radiator of the at least one radiator. Each radiator of the at least one radiator is associated with at least one passage having an entry end in communication with one surface of the radiator and an exit end adjacent the entry end of one duct of the ducted fans.
Abstract:
Described herein are tissue grafts derived from the placenta. The grafts are composed of at least one layer of amnion tissue where the epithelium layer has been substantially removed in order to expose the basement layer to host cells. By removing the epithelium layer, cells from the host can more readily interact with the cell-adhesion bio-active factors located onto top and within of the basement membrane. Also described herein are methods for making and using the tissue grafts. The laminin structure of amnion tissue is nearly identical to that of native human tissue such as, for example, oral mucosa tissue. This includes high level of laminin-5, a cell adhesion bio-active factor show to bind gingival epithelia-cells, found throughout upper portions of the basement membrane.
Abstract:
A supervisory communications device, such as a headend device within a communications network, monitors and controls communications with a plurality of remote communications devices throughout a widely distributed network. The supervisory device allocates bandwidth on the upstream channels by sending MAP messages over its downstream channel. A highly integrated media access controller integrated circuit (MAC IC) operates within the headend to provide lower level processing on signals exchanged with the remote devices. The enhanced functionality of the MAC IC relieves the processing burden on the headend CPU and increases packet throughput. The enhanced functionality includes header suppression and expansion, DES encryption and decryption, fragment reassembly, concatenation, and DMA operations.

Abstract:
A sports apparatus for throwing and catching a projectile, comprising a frame having a handle, catching means arranged on the frame, and throwing means arranged on the frame. The throwing means comprises a gripping component that is arranged to partially surround and releasably grip and retain a projectile therein, and a retained projectile may be released from the throwing means upon acceleration of the frame.
Abstract:
A method for preparing placenta membrane tissue grafts for medical use, includes obtaining a placenta from a subject, cleaning the placenta, separating the chorion tissue from the amniotic membrane, mounting a selected layer of either the chorion tissue or the amniotic membrane onto a drying fixture, dehydrating the selected layer on the drying fixture, and cutting the selected layer into a plurality of tissue grafts. Preferably, the drying fixture includes grooves or raised edges that define the outer contours of each desired tissue graft, after they are cut, and further includes raised or indented logos that emboss the middle area of the tissue grafts during dehydration and that enables an end user to distinguish the top from the bottom side of the graft. The grafts are comprised of single layers of amnion or chorion, multiple layers of amnion or chorion, or multiple layers of a combination of amnion and chorion.

Abstract:
Control of transgene expression in planta is dependent upon genetic elements that affect both transcription and translation of mRNA transcripts. The disclosed invention describes the combination of DNA elements from four different plant viruses that function as an activator of transcription and enhancer of translation of mRNA transcripts in transgenic plants.

Abstract:
A method for increasing upstream bandwidth per cable modem user in a cable communications system that includes a cable modem termination system (CMTS) and a plurality of cable modems is provided. The method permits a cable modem to transmit data to the CMTS on multiple upstream channels simultaneously using a technique called “channel bonding.” Channel bonding allows smaller bandwidth upstream channels to be bonded together to create a larger bandwidth pipe.
