Abstract: The present invention relates to a novel garden spade wherein the scoop portion has straight sides. In addition, the proximal end of the scoop has a hammer plate uninterrupted by the neck which neck is attached to the scoop of the spade distal to the hammer plate. The neck and handle attached to the neck are angled such that the hammer plate can be struck with the greatest amount of clearance and best angle of attack for hitting a spade compared to previous spades which are not designed to successfully be hit without damage to either the spade, the user or both.

Abstract: An embodiment of the invention is a method of helping establish optimal latency in audio streaming applications over a packet switched network. The method involves determining whether an elapsed time between arrival of first and second packets, the packets being parts of a stream of audio sent by a transmit process through the network and received by a receive process, is primarily a network delay due to the second packet being slowed while traveling through the network, or primarily a transmit delay due to a delay by the transmit process in sending the second packet. The elapsed time is included as part of interpacket delay statistics only if it is determined that the elapsed time is primarily due to the network delay. The latency may then be adjusted by adjusting the size of a packet queue based on more accurate interpacket delay statistics.

Abstract: A control circuit and auxiliary power supply and a switching means for connecting the load selectively to the auxiliary power supply and the main power supply.The main power supply may be a public utility power line, and the auxiliary power supply is a windmill, a motor and generator all connected together on a common shaft. A control means senses the output voltage of the generator or output frequency and controls the switch to either connect the load to the power line or the auxiliary power supply.A battery is supplied for storing excess windmill power and for driving the motor and generator during periods of low wind.
