Abstract: Techniques for assessing risk associated with firewall rules are provided. In one implementation, a method includes receiving a request for the network to apply a firewall policy rule to control traffic to a machine associated with the network, wherein the firewall policy rule comprises information that identifies a remote address from which the traffic can originate and a type of the traffic. The method further includes determining a remote address risk value representative of a first degree of security risk associated with allowing the traffic to access the machine in response to the traffic being determined to originate from the remote address; determining a traffic type risk value representative of a second degree of security risk associated with allowing the type of traffic to access the machine; and determining a total risk value based on a combination of the remote address risk value and the traffic type risk value.

Abstract: Embodiments of a personnel basket for attachment to a crane boom include folding sidewall sections; a rear wall connected to the sidewall sections; a front wall in pivotal connection to one of the folding sidewall sections; a floor in pivotal relation to the rear wall; and a stalk connected to the rear wall and including a boom connection. Because of the pivotal relationships, the personnel basket is moveable or foldable in a connected or assembled condition between a deployed (unfolded) state and a folded (fully collapsed) state. When in the deployed state, the folding sidewall sections are in a vertical orientation and perpendicular to the vertically oriented rear and front walls and the horizontally oriented floor. When in the folded state, the folding sidewall sections remain vertically oriented, as do the rear and front walls, but overlap and are parallel to the rear and front walls and the floor.

Abstract: A process and system are disclosed for the biofiltration of volatile organic compounds. The process involved recirculating contaminated effluent gas through a biofilter (1), the biofilter (1) having an inlet (20), outlet (15) and micro-organism laden filter media bed (3). The filter media bed additionally having moisture retaining properties. This process has been effective in removing high levels of VOCs from effluent gas streams and also in removing VOCs from an effluent gas stream where the VOC levels and/or volumes of effluent gas vary over time.

Abstract: A method of verifying integrity of an access point on a wireless network comprises registering an access point with a core network, allocating a unique identifier from the network to the access point; recording data including the unique identifier together with a geographical location of the access point; requesting reports relating to access points in the vicinity of a mobile terminal when the mobile terminal sends other data, including the unique identifier as determined by mobile terminals listening to wireless transmissions from said access points, to the core network; and checking data in the reports against recorded data to determine if an access point is genuine

Abstract: A method of authenticating access points (1, 2, 3) on a wireless network (4) comprises sending a list of nearest neighbours (2, 3) from a trusted access point (1) to a controller (6). At the trusted access point (1), test data related to each of the listed nearest neighbours is received from the controller. Each neighbour (2, 3) is interrogated using its respective test data and the response compared with an expected response. A reliability indication is returned to the controller (6).

Abstract: A loudspeaking telephone instrument comprises a transmit path comprising a microphone (1) and comb filter (2); a receive path comprising a comb filter (3), a frequency shifter (4) and a loudspeaker (5); and a hybrid circuit (6). The frequency shifter (4) shifts the frequency of a signal applied to its input by a fixed amount and the comb filters (2,3) are arranged so that the frequency shifted signal falls in their stop bands. This increases the available gain in the loudspeaking telephone instrument before instability occurs. The spacings of the pass and stop bands of the comb filters (2,3) are at a multiple of the frequency by which the frequency shifter shifts that of its input signal.

Abstract: A telephone set comprising an input unit, a signal generating unit and an information processing unit, which may comprise a read-only memory, a microprocessor or a special LSI circuit for converting information supplied by the input unit into information to be transmitted. In order to obtain a greater reliability as a telephone set, a supervisory circuit, a switching unit and a d.c. isolated signal path have been provided between the switching unit and the information processing unit for coupling the input unit to the signal processing unit via the d.c. isolated signal path and for, possibly, coupling the signal processing unit to the signal generating unit when the supervisory circuit detects proper operation of the information processing unit and for connecting the input unit to the signal processing unit when the supervisory circuit detects a faulty operation of the said information processing unit.

Abstract: A DC supply for an electronic signalling device that is connected to a signal transmission line. The device comprises a plurality of circuit units each of which must be supplied with a DC-supply current. Feeding the circuit units in series has the advantage that the DC-supply current in each of the circuit units can be utilized to the full. A drawback is that the different supply voltages add up. A practical requirement may be that the total supply voltage does not exceed a certain value at a certain value of the supply current. In order to satisfy this requirement means are present which cause the supply voltage of one of the circuit units to decrease more than proportionally to the DC-supply current when the DC-supply current decreases to below a certain value.The invention is suitable for use in loud-speaking telephone sets.
