Abstract: A flameless electric candle having a fan-driven scent diffuser. The candle includes a body portion having a translucent portion and a generally elongated cylindrical shape and housing therein a light emitting device configured to permit its emitted light to be partially visually discernible through the translucent portion. There is below the body portion, a base portion that includes a PCB, a switch, a light emitting device, a power source, a fan oriented to force air in a downwards direction away from the body portion, a pad configured to receive upon a surface thereof a fragrance or scent, openings in a wall of the base portion to allow the forced air scented by the fragrance to escape the base portion. The switch is selectable among a first mode in which the LED and fan are both on, an off mode both the LED and fan are off, and a second mode wherein only one of the LED or fan is on.

Abstract: A mobile communication device (100) uses a local wireless transceiver (108) to establish an asynchronous link (202) with a remote audio processor (110) which is typically operated in a low power mode and that maintains an association between the mobile communication device and remote audio processor. When the mobile communication device receives an incoming call page (210), the mobile communication device initiates a synchronous link with the remote audio processor, and responds to the incoming call page at a time when the call will be connected only after the synchronous link is established.

Abstract: A mobile communication device (100) contains a local wireless controller (114) for operating with a remote audio processor (124). The remote audio processor is used for listening to and speaking with remote parties via the mobile communication device, and operates in a mode having a relatively long latency in communicating with the mobile communication device. Upon receiving a dispatch call (306), a baseband processor (108) of the mobile communication device notifies an application processor (110) with a high priority dispatch notification (122). The high priority dispatch notification causes an active link to be established between the mobile communication device and remote audio processor sooner than if were to occur with ordinary call processing.

Abstract: Apparatus and methods for managing key material in cryptographic assets are disclosed. The methods can include defining first key material to be delivered to a cryptographic asset, wherein the first key material has a cryptoperiod having an expiration. Second key material to be delivered to the cryptographic asset is also defined. An automatic delivery of the second key material is scheduled such that the second key material will be delivered automatically to the cryptographic asset at or before the expiration of the cryptoperiod of the first key material. The methods can include defining a set of equipment classes, and registering at least one cryptographic asset with each equipment class. Cryptographic assets selected from the registered cryptographic assets are grouped into secure communication services, thereby defining secure communication interfaces between the cryptographic assets.

Abstract: Apparatus and methods for remotely rekeying a cryptographic device are disclosed. A method according to the invention includes associating a preliminary certificate with the device, generating a device certificate associated with the device, determining whether a certificate stored in the device is the preliminary certificate associated with the device, and if the certificate stored in the device is the preliminary certificate associated with the device, then securely loading the device certificate into the device. Apparatus for remotely rekeying a cryptographic device includes a computer readable medium having stored thereon computer executable instructions for performing a method according to the invention.

Abstract: A lead anode for electrowinning metals from sulfuric acid solutions is formed by soldering a sheet of lead anode material endwise in a slot, which extends longitudinally along and partially through a lead alloy coated copper bus bar and into which the sheet fits tightly, and thereafter depositing lead alloy filler at all joints between the bar and anode. Anodes thus constructed have a uniform, smooth joint between the bar and sheet and thus are corrosion resistant and exhibit uniform conductivity.

Abstract: An inclined pair of stringer beams carries a plurality of transverse steps supported on saddles secured to the stringers. The upper tread surfaces of the steps are planar whereas the lower surfaces are arcuate, with a predetermined radius of curvature matching the corresponding arcuate shape of the subjacent supporting saddles.By angularly tipping each of the steps to or fro in the respective pair of saddles, the upper tread surface of the steps can be leveled despite variations in the angle of inclination of the stringers.The step is ordinarily constructed of precast concrete and includes metal reinforcements as well as metal inserts affording anchor points for attachment to the saddle, as by threaded fastenings or by welding.
