A process and apparatus to facilitate communication between callers and callees in a system comprising a plurality of nodes with which callers and callees are associated is disclosed. In response to initiation of a call by a calling subscriber, a caller identifier and a callee identifier are received. Call classification criteria associated with the caller identifier are used to classify the call as a public network call or a private network call. A routing message identifying an address, on the private network, associated with the callee is produced when the call is classified as a private network call and a routing message identifying a gateway to the public network is produced when the call is classified as a public network call.

A method of assaying potentially radioactive material comprises selecting a plurality of samples from a material mass on a site (200). In a sequence of steps (104, 106, 108, 110, 112), an activity measurement based on a gross count of each of the samples (212) in the plurality of samples is performed on the site (200), and the activity measurement is compared with one or more activity thresholds in order to categorise the radioactive material for disposal purposes. The threshold(s) and/or activity measurement are based on an assumed parameter set. In a further step (114), sample x from every y of the plurality of samples is selected, where x

A system includes a non-vertical channel containing a fluid forming a fluid meniscus having a capillary length and a contact angle θ. The channel in cross-section has a perimeter length |Σ |and an area |Ω|. The cross-section of the non-vertical channel is selected so as to define a constant Lagrange multiplier λ, where λ= |Σ |cos θ / |Ω|. A functional Φ [Γ*] Ξ |Γ*| – cos θ |Σ* | + (1/a 2 ) G* +λ |Ω*| is minimised to define a minimum value Φ 0 =MinΦ. At a critical transition where Φ=0, the fluid defines a smooth arc of length [Γ*] that divides the cross-section of the channel into two parts. |Ω*| is the cross-sectional area of the fluid, which has a curve of length |Σ* | in contact with the channel, and G* represents a vertical position of the centre of mass of the fluid multiplied by the cross-sectional area |Ω*|. How far the fluid meniscus extends along the channel is controlled by one or more parameters of the functional Φ [Γ*].

In one aspect, a device (100) includes: a display (110) configured to display symbols; a processor (112); and a computer-readable medium having stored thereon program instructions, that when executed by the processor (112), cause the device (100) to perform a set of acts including: selecting a first symbol-set from a global symbol-group, wherein the first symbol-set includes at least two symbols; displaying on the display (110) the selected first symbol-set; making a determination that a second symbol-set, which is a proper sub-set of the selected first symbol-set, satisfies a trigger condition; after making the determination, (i) selecting a first supplementary-symbol from a first supplementary symbol-group different from the global symbol-group and (ii) selecting a second supplementary-symbol from a second supplementary symbol-group different from the global symbol-group; displaying on the display (110) the selected first supplementary-symbol; displaying on the display (110) the selected second supplementary-symbol; determining a first amount based, at least in part, on the selected first symbol-set; determining a second amount based, at least in part, on the selected first supplementary-symbol and the selected second supplementary-symbol; determining a payout amount based on a function of the determined first amount and the determined second amount; and displaying on the display (110) the determined payout amount.

A method of producing a localised concentration of energy includes: creating at least one shockwave propagating through a non-gaseous medium so as first to be incident upon a focusing pocket of fluid within the medium. The focusing pocket of fluid is positioned relative to a differently sized target pocket of gas within the medium, and is arranged to shield the target pocket of gas from the initial shockwave, such that the incidence of the shockwave on the focusing pocket of fluid concentrates the intensity of a shockwave subsequently incident upon the target pocket of gas. An apparatus for producing a localised concentration of energy is also described.

A method of producing a localised concentration of energy includes: creating a shockwave propagating through a non-gaseous medium so as to be incident upon a boundary between the non-gaseous medium and a gaseous medium formed by at least one hole in a barrier separating the non-gaseous medium from a gaseous medium. This forms a transverse jet on the other side of the hole which is incident upon a target surface comprising a depression which is spaced from the barrier in the gaseous medium. An apparatus for producing a localised concentration of energy is also described.

An apparatus for tying a wire (46) around one or more objects (2) has means for passing said wire in a loop around the objects and means for twisting the ends of said loop together. The twisting means includes at least one gripping means (32) for gripping the wire so that the wire does not slip therethrough. The apparatus also comprises means (54) for applying a biasing force between the twisting means and an object (2) being tied such that as the wire (46) is twisted the twisting means is drawn towards the object (2) against the biasing force.

LED based lamps and bulbs are disclosed that comprise an elevating element to arrange LEDs above the lamp or bulb base. The elevating element can at least partially comprise a thermally conductive material. A heat sink structure is included, with the elevating element thermally coupled to the heat sink structure. A diffuser can be arranged in relation to the LEDs so that at least some light from the LEDs passes through the diffuser and is dispersed into the desired emission pattern. In some lamps and bulbs utilize a heat pipe for the elevating elements, with heat from the LEDs conducting through the heat pipe to the heat sink structure where it can dissipate in the ambient.
摘要:
An LED with improved current spreading structures that provide enhanced current injection into the LED's active layer (14), improving its power and luminous flux. The current spreading structures can be used in LEDs larger than conventional LEDs while maintaining the enhanced current injection. The invention is particularly applicable to LEDs having insulating substrates (12) but can also reduce the series resistance of LEDs having conductive substrates. The improved structures comprise conductive fingers (20a, 20b, 22) that form cooperating conductive paths that ensure that current spreads from the contacts (19, 21), into the fingers (20a, 20b, 22) and uniformly spreads through the oppositely doped layers (15, 16). The current then spreads to the active layer (14) to uniformly inject electrons and holes throughout the active layer (14), which recombine to emit light.
