An access method for periodic contention-free sessions (PCFS) reduces interference between overlapping first and second wireless LAN cells contending for the same medium. Each cell includes a respective plurality of member stations and an access point (AP) station. The access method for periodic contention-free sessions (PCFS) includes a fixed cycle time that reduces conflicts with PCFS from other cells. The PCFS from several cells are repeated in cycles of cycle period (CP), which is the contention-free period (CFP) of an access point times a factor that is a function of the number of overlapping cells. Periodic contention-free sessions (PCFSs) are generated, one from each overlapping cell. PCFS transmission attempts occur at the fixed specified time spacing following the start of the previous cycle. Each active AP sets a timer at CP and a PCFS is initiated when the timer expires. The timer is then reset to CP and this starts a new cycle. Contention transmissions are attempted by stations based on their assigned priority. If a channel is busy at the designated start time for transmitting a PCFS, the PCFS is shortened by the time lost. Interleaving PCFSs and CFSs reduces conflicts with CFSs from other cells. To lessen the contention between APs of different cells, each station's Network Allocation Vector (NAV) and Inter-BSS Network Allocation Vector (IBNAV) is updated by an increased value of the next CFS length, the increment being the inter-BSS contention period (IBCP). APs will attempt to access the channel during the IBCP only for transmitting a PCFS, while they will wait for the NAV and IBNAV expirations before attempting to transmit a CFS. Interleaving PCFSs and CFSs also enables maintaining quality of service (QoS).

Each flank insert includes an under side, an opposite upper side, and a circumferential edge side that forms a rake face connecting the upper side and the underside.

The present invention is directed to a heat exchanger for an automotive vehicle. The heat exchanger includes a first end tank divided into a first portion and a second portion by a baffle, the first end tank including a through-hole.

The baffle system includes a baffle or baffles with a central portion and at least one flanged peripheral portion, the flanged peripheral portion having a peripheral channel. Additionally, the baffle preferably is disposed within the end tank so that the peripheral channel is substantially juxtaposed with the through-hole in the end tank for providing a visual leak indicator.

An ion spectrometer is provided, comprising: an ion source, arranged to generate ions continuously with a first range of mass to charge ratios; and an ion trap, arranged to receive ions from the ion source along an axis, and to eject ions with a second range of mass to charge ratios orthogonally to that axis, the second range of mass to charge ratios being narrower than the first range of mass to charge ratios. In some embodiments, ions generated by the ion source continuously flow into the ion trap. Additionally or alternatively, ion optics receive ions ejected from the ion trap and cool the ions without substantial fragmentation. An ion analyser receives ions ejected from the ion trap or ion optics and separates the ions in accordance with at least one characteristic of the ions.

The Y-piece (12) is provided with a flow measuring sensor (2) having pressure lines (3) connected to the measuring device. The pressure lines (3) are arranged to run inside of an outer wall surface of the flow measuring sensor (2).

A defence system for a land area, intended as an alternative to land mines. The system includes sensors for detecting intrusions in the area, a weapon having multiple barrels and multiple projectiles ready for firing, and a controller that receives signals from the sensors to fire the weapon. The controller preferably requires intervention of an operator in order to trigger the weapon. The weapon may contain a range of projectiles for different purposes.

This invention relates to a monitoring method and system for monitoring the dispensing of medicaments in a hospital from a portable medicament dispensing station. The medicament dispensing station 3 has a first identification means 9 and a second identification means 13 for capturing identifiers relating to an individual wishing to dispense a medicament. A releasable locking mechanism 23 is provided that will allow dispensing of medicaments on appropriate identifiers being captured and authenticated. The identifier data is transmitted to a monitoring unit 5 over a communications network 8 and is stored in a remote monitoring unit memory 7 for future reference. By implementing such a system and method, tampering with the data input to the system is obviated and traceability and accountability are facilitated.
