A virtual machine management apparatus connected to a plurality of server devices via a network generates a new virtual machine on a server device in accordance with a request from a management terminal. At that time, for one or more server devices to which a new virtual machine can be allocated, the virtual machine management apparatus refers to an allocation rule table for storing a score for each of combinations of types of virtual machines. The score indicates appropriateness of a condition that each combination of types of virtual machines is to be allocated to the same server device. Thus, the virtual machine management apparatus computes an index value indicative of appropriateness of a condition that the new virtual machine is to be allocated to the server device. Then the virtual machine management apparatus determines an allocation target for the new virtual machine with reference to the computed index value.

An F-inverted compact antenna for ultra-low volume Wireless Sensor Networks is developed with a volume of 0.024λ×0.06λ×0.076λ, ground plane included, where λ is a resonating frequency of the antenna.

An exposure apparatus (EX) exposes a substrate (P) by projecting an image of a pattern on the substrate (P) via a projection optical system (PL) and a liquid (1). The exposure device (EX) has a liquid supply mechanism (10) which supplies the liquid (1) between the projection optical system (PL) and the substrate (P). The liquid feeding mechanism (10) stops the supply of the liquid (1) when abnormality is detected. This suppresses influence to devices and members in the periphery of the substrate caused by leakage of the liquid forming a liquid immersion area, thereby realizing satisfactory exposure processing.

An implantable device, such as an infuser device for bidirectional hydraulically controlling a medical artificial sphincter, enhances power transfer characteristics to a secondary coil thereby allowing implantation to greater physical depths and/or enclosing the secondary coil within a housing of the infuser device. The enhanced power transfer is achieved with multiple coils that are longitudinally aligned and physical and electrical parallel to form the secondary loop of a transcutaneous energy transfer system (TET) instead of a single coil. It better optimizes the power transfer from a parallel tuned tank circuit primary coil to an implanted secondary series tuned tank circuit coil.
