Title: A method for a simple 802.11e hcf implementation
Inventor: MEIER ROBERT
IPC: H04L12/28
Filed: 2004-03-18
Abstract: A Hybrid Coordination Function (HCF) implementation wherein an access point's existing (E)DCF Enhanced Distributed Coordination Function transmit queues are augmented by at least one strict priority HCF transmit queue. The HCF queues are only used to schedule downlink data and CF-Poll transmissions are used for admitted downlink flows and for uplink flows. The 802.1D user priority value is used to select the HCF queue for an admitted flow. The strict priority HCF  transmit queues are always serviced first, in priority order before any other (E)DCF transmit queue. The channel is considered busy to (E)DCF transmit queues while the strict priority queues are being serviced. An admissions control mechanism is used to control data flows and prevents the strict priority traffic from starving (E)DCF traffic. A single, simple AP scheduler is used for scheduling both polling times and station wakeup times. Different embodiments of the invention includes assigning a fixed size to all transmission opportunities, the establishment of a wakeup schedule for a power-save station, the implementation of a polling schedule for the station, the establishment of a schedule based on a timer wheel, and the allocation of a token bucket for a data stream with a predetermined number of tokens.

Abstract: A system and method of packet zone hysteresis for a mobile station is presented. A packet zone hysteresis reset timer is started whenever the mobile station sends or receives packet data and packet data exchange is determined to be incomplete. The packet zone hysteresis reset timer gives a time duration for which packet data exchange must be completed if packet zone hysteresis information is to be maintained. If the packet zone hysteresis reset timer expires before packet data exchange is completed, then the packet zone hysteresis information is cleared. If the mobile station moves to a different packet zone while packet data exchange is determined to be incomplete or packet data is going to be sent to which a response is expected, then the mobile station will perform a packet data reconnect. According to another aspect, upon detecting that a packet data exchange has completed, the mobile station re-activates packet zone hysteresis if it was de-activated from the packet data exchange.

IPC: A01M1/08
Filed: 2006-04-06
Abstract: A device integrating light and suction to eliminate flying insects named BUG-VAC  LIGHT. The invention is an electrical lamp integrating suction within the unit's body.  The light and heat generated by the lamp attract bugs while the suction aspirates them, trapping and killing flying insects. The device uses a weatherproof motor with patented Seabreeze Turbo-Aire fan to generate suction by the aerodynamics created in the Bug--Vac chamber.    A butterfly trap at the bottom of the chamber opens from the air flow when the device is on, thereby aspirating the insects into the receptacle where the bugs remain trapped because of the constant flow of air. The insects die from battering caused by the tornado effect produced by the wind tunnel in the receptacle, which propels the insects, upon entry, against the receptacle walls. Moreover, the strong air current in the receptacle prevents air intake by the insects, which then expire through asphyxiation;  the constant air flow and heat from the light helps to dehydrate the trapped insects.   The light attracts insects from far thereby contributing a large trapping circumference, while the heat generated by the light invites the insects to hover near it where suction then draws the insects into the receptacle. The air current generated by the Turbo-Aire fan causes suction to project beyond the receptacle creating an invisible air tunnel outside of the receptacle in order to catch insects in flight. Once caught in the air current, insects are aspirated into the receptacle.   Both the attractant and the trap are mechanical in nature, requiring no chemicals or repellents that may be toxic to humans and animals. The device is designed to eliminate insects rather than to simply repel them, so as to prevent nesting and breeding of insects, and thereby curbing dissemination of diseases associated with flying insects. The device is entirely ecological in its construction, functioning and usage.  The housing is a combination of a polymer and aluminium to create a weatherproof unit that can be used outdoors as well as indoors. The device is power operated, requiring clean electrical energy only to function. The receptacle is so designed as to provide easy-cleaning and the opportunity to collect the dead insects and use them to feed birds, reptiles or fish to fully exploit the ecological concept.

Title: Method of rotating a polyphase motor at less than rated speed
Inventor: BARIE WALTER G
IPC: H02P25/22
Filed: 2006-05-31
Abstract: A polyphase AC induction motor is connected to a power supply through a soft starter having three sets of inverse parallel connected silicon controlled rectifiers with each set corresponding to one particular phase. Low speed starting and operation of the motor can be accomplished through triggering circuits controlling the phases of the triggering pulses in relation to the phases of the supply. The low motor speeds are developed by a gating sequence that generates a low frequency waveform that is less than the main supply frequency to the motor. This low frequency waveform is current and voltage controlled by the gating sequence to permit the AC motor to smoothly operate at speeds less than 100% of rated while developing net positive torque at the low controlled operating frequency.

Title: Transfer of attributes between geometric surfaces of arbitrary topologies with distortion reduction and discontinuity preservation
Inventor: COUTURE-GAGNON JEROME
IPC: G06T17/20
Filed: 2006-07-26
Abstract: Attributes associated with components of a three-dimensional source geometry may be transferred to a target geometries having an arbitrarily different topology.  The two geometries are placed in a general alignment in three dimensions.  Correspondences are found between anchors for attributes in the target geometry and anchors for attributes in the source geometry. The identified correspondence locations on the source geometry are locally redistributed so as to ensure that concave regions of the source geometry are mapped to the target geometry, and that convex edges or vertices of the source geometry do not map to a large area on the target geometry. Attribute discontinuities in the source geometry are preserved in the target geometry by relating discontinuous edges in the source geometry to the target geometry. This relationship may map each discontinuous edge in the source geometry locally to the target geometry. Alternatively, this relationship may involve mapping discontinuous paths globally to the target geometry. Thus, the quality of attribute transfer is improved by reducing distortions introduced by the method through which correspondence between a target geometry and a source geometry is determined and/or by preserving discontinuities in attributes from the source geometry by relating discontinuous edges in the source geometry to the target geometry.

Title: Lyophilization method to improve excipient crystallization
Inventor: KNOWLES SUSAN
IPC: C12N7/00
Filed: 2005-03-04
Abstract: The present invention provides improved methods to lyophilize (freeze-dry) active ingredients such as proteins, nucleic acids and viruses. The present methods improve the degree of excipient crystallization during lyophilization over prior methods. The improvement in excipient crystallization is based, in part, on a high-temperature annealing step that is conducted prior to or at the same time as secondary drying. Importantly, the high~temperature annealing step does not destabilize active ingredients. Further, the high~temperature annealing step does not require sub-zero annealing steps prior to its enactment in order to provide complete excipient crystallization.
