Abstract: A combination of repeaters and relays is used to improve the data throughput for user equipment (“UE”) near the cell edge in a LTE network. Amplify-and-forward repeaters and decode-and-forward relays enhance the down-link and up-link, respectively. Relay assistance on the up-link occurs when the evolved Node B (“eNB”) requests a retransmission (HARQ) from the UE at which point the UE and relay transmit simultaneously in a cooperative fashion. The quality of the up-link signal received by the eNB is improved due to a favorable channel through the relay. An analysis shows that relay assistance improves the throughput for a cell-edge user when the average delay per data transport block is allowed to increase.

Abstract: This invention encompasses embodiments for multi-modal integrated simultaneous measurement of various aspects of fluids contained in circulating systems such as automotive reciprocating engines and vehicle transmissions. These circulating systems perform constant internal lubrication, and heat and contaminant removal to protect the internal moving parts from the inherent friction and damage in normal operation. Most commonly this is achieved with fluids based on hydrocarbon and/or related synthetics, which, over time, can lose their protective properties, and vary in their performance or breakdown/decay due to internal and external events. Several components within the lubricant fluid can be measured and can provide insight into the efficacy of the system to perform its designed mission. Described herein is a real-time, simultaneous, integrated, multi-modal sensor system for early warning notification.
