摘要:
A process for cooperative aerial inter-antenna beamforming for communication between (a) multiple moving platforms, each platform having an aerial antenna mounted thereon, such that the aerial antennas have variable positions and orientations over time, and (b) at least one antenna mounted on user equipment having a lower altitude than the aerial antennas; the process involving transmitting data relating to the positions and orientations of the aerial antennas to a processing system, the processing system calculating and transmitting beamforming instructions to the aerial antennas, the aerial antennas thereby transmitting or receiving respective component signals for each user antenna, the component signals for each user antenna having essentially the same information content but differing in their phase and usually amplitude, so as to form a cooperative beam from the cooperative sum of the signals between the aerial antennas and the user antenna. A method of determining the position of a moving aerial antenna or antenna element mounted on at least one moving platform, such that the aerial antennas have variable positions and orientations over time, the method involving determining the phase difference yi, being a fraction of a wavelength between the values 0 and 1, between signals of known wavelength λi; transmitted between (a) i ground based transmitters which may be backhaul base stations, wherein i is at least three, the ground based transmitters having known position to within λi/10 and (b) the aerial antenna or antenna element, thereby establishing the distance from the base station to the aerial antenna or antenna element to be λi(ni+yi), wherein ni is an unknown integer; determining the position of the aerial antennas or antenna elements approximately by differential GPS or other methods to within a small number of wavelengths λi thereby establishing that ni can be one of a limited number of possible integer values for each signal; the number of base stations and their positions being sufficient to allow elimination of the possible values of ni that are inconsistent with the limited number of possible values for ni from the other ground based transmitters, until only one integer value for each ni is established; establishing the location of the aerial antenna or antenna element by triangulation of its known distance λi(ni+yi), from at least three ground based transmitters.

A method, an apparatus, and a computer program product for managing a set of passwords for online services. The apparatus determines a current set of passwords associated with the user for the online services. The apparatus determines at least one criterion that excludes user intervention for refreshing passwords to the remote systems. The apparatus detects at least one trigger condition matching the at least one criterion that excludes user intervention for refreshing the passwords to the remote systems. Upon detecting the at least one criterion condition, generating a new set of passwords and transmitting at least one command including the new set of passwords to the remote systems.

An apparatus includes first and second fixation members, a flexible member coupled to the first and second fixation members, and a limiting element coupled to the flexible member. The limiting element is movable relative to the second fixation member and acts to limit loosening of the flexible member relative to the second fixation member. The limiting element can be slidably received by the flexible member. The flexible member can be coupled to the fixation members such that pulling on a free end of the flexible member shortens a length of the flexible member between the fixation members.
摘要:
A method of determining the performance of a processor when processing a unit of data is described. The method comprises the steps of: receiving, at a first sample rate, information indicating the performance of the processor when processing the unit of data; generating an identifier that identifies the unit of data being processed; comparing the identifier with previous identifiers at a second sample rate; and outputting the identifier of the unit of data being processed and the performance information when, during the comparing step, a predetermined condition is met.

A computing device is disclosed for securely sharing restricted content. The computing device includes a memory storing computer readable instructions, and one or more processors configured to execute the computer readable instructions. The computer readable instructions configure the one or more processors to, collectively, receive a share request to share the restricted content; in response to the share request, encode a link with encrypted access information, the access information including a first password and identifying the restricted content; receive an access request for access to the restricted content from a client device executing the link, the access request including the encrypted access information; receive a second password from the client device in association with the access request; and grant the client device access to the restricted content in response to determining the first password matches the second password. A method and a computer readable medium are also disclosed.
