Abstract: A heatsink comprising a heat exchange device having a plurality of heat exchange elements each having a surface boundary with respect to a heat transfer fluid, having successive elements or regions having varying size scales. According to one embodiment, an accumulation of dust or particles on a surface of the heatsink is reduced by a removal mechanism. The mechanism can be thermal pyrolysis, vibration, blowing, etc. In the case of vibration, adverse effects on the system to be cooled may be minimized by an active or passive vibration suppression system.

Abstract: The present invention pertains to improved communication quality and security of transmission in cellular communication networks. A customer has the option to pay different fees for different tiers of service relating to voice quality, bandwidth access, and different tiers of service relating to communications security. Higher tiers may guarantee a specific vocoder or bit rate is used, or guarantee a specific encryption protocol is use to ensure secure communications. Different tiers may be associated with customers' records for billing purposes. The network may afford high end devices higher voice quality and/or security via a lookup table indicating what level of service is associated with a given device. Calling or receiving devices may negotiate with each other to change to a more robust vocoder or bit rate to ensure a higher quality and/or security. Furthermore, the user may opt to change the quality and/or security level before or during a call.

Abstract: A heatsink comprising a heat exchange device having a plurality of heat exchange elements each having a surface boundary with respect to a heat transfer fluid, having a fractal variation therebetween, wherein the heat transfer fluid is induced to flow with respect to the plurality of fractally varying heat exchange elements such that flow-induced vortices are generated at non-corresponding locations of the plurality of fractally varying heat exchange elements, resulting in a reduced resonance as compared to a corresponding heat exchange device having a plurality of heat exchange elements that produce flow-induced vortices at corresponding locations on the plurality of heat exchange elements.

Abstract: The present invention provides systems and methods for supporting encrypted communications with a medical device, such as an implantable device, through a relay device to a remote server, and may employ cloud computing technologies. An implantable medical device is generally constrained to employ a low power transceiver, which supports short distance digital communications. A relay device, such as a smartphone or WiFi access point, acts as a conduit for the communications to the internet or other network, which need not be private or secure. The medical device supports encrypted secure communications, such as a virtual private network technology. The medical device negotiates a secure channel through a smartphone or router, for example, which provides application support for the communication, but may be isolated from the content.

Abstract: The present disclosure pertains to improved communication quality of service (QoS) in communication networks. Higher service tiers may guarantee that a specific vocoder or bit rate is used. They may also guarantee that communication is supported by such parameters as maximum allowed dropped calls rate, maximum allowed jitter and maximum allowed latency. Network availability may be guaranteed per Service Level Agreements that are the part of the contract between a subscriber and a service provider. The network may also afford high end devices higher voice quality by comparing a given high end device to a look up table, which indicates what level of service is associated with that device. A calling device or a receiving device may ask the other device to change to a more robust vocoder or bit rate to ensure higher quality communication. Furthermore, the quality level may be adjusted before or during a call.
