Abstract: To reduce the load on a management server in a load distributed system, a server list manager 16 of a management server 10 selects servers 4, 6, 20, and 30 to be accessed by a client terminal management server 43 by referencing an operation status or a load status of the servers 4, 6, 20, and 30, generates a server list, and sends the generated server list to the client terminal management server 43. An inquiry unit 47 of the client terminal management server 43 regularly sends an inquiry to the network monitoring server 30, which is included in the server list 45, to ascertain whether or not information has been updated. If the information has been updated, an information collection unit 48 acquires a corresponding latest module and a rule base from the information providing server 20 included in the server list 45 based on information from the network monitoring server 30.

Abstract: In order to simplify prevention of unauthorized or malicious electronic mail transmission, a mail server comprises a password conversion table which shows registered correlation among user ID, a formal password, and a virtual password different from the formal password, both assigned to each user for user authentication by a general-purpose mail server. A user is informed of only a virtual password. When electronic mail having a virtual password and addressed to an outsider of a company is sent from a client PC, a password conversion processor converts the virtual password into a corresponding formal password with reference to the password conversion table, and the virtual SMTP server function processor sends the electronic mail now having the formal password to the general-purpose mail server. A user at a client PC cannot access the general-purpose mail server using a virtual password as the user is not authenticated using the virtual password.

Abstract: A method for assigning setting information to a client suitably distributes clients among gateways which are used for connection to an external network. A server assigns gateways to each client in order such that the load placed onto the gateways can be distributed. When a request for extension of use is received from a client A which uses GW1 after a failure has occurred in GW1, the server assigns GW2 which is available. In this process, a lease period is set at a shorter time than the base lease period. When a request for extension of use is received from the client A after GW1 is restored, the server returns the gateway to be used to GW1.

Abstract: An information collection apparatus working as an agent of a plurality of client terminals for collecting information from an information providing server. A plurality of requested-item lists are stored in the requested-item list table, one for each client terminal. Each requested-item list is composed of a plurality of requested-items identifying a plurality of information items to be obtained by each client terminal. An information manager, which has the function of a combining processor, combines the contents of a plurality of requested-item lists to create a collection list. The collection list is composed of a plurality of collection items identifying a plurality of information to be collected by the information collection apparatus. The collection list is stored in a collection list table. An information collection processor actively references the information providing server to check if information has been updated, based on the collection list. Updated latest information is collected in this way.

Abstract: In a method for preferably assigning, to a client, setting information necessary for connection to an external network, an address assignment processing section of a server which is a coordinator server at that point assigns an IP address and GW address and returns the assigned information to the client in response to an address assignment request from the client. The address assignment processing sections of servers which will become, through a server circulation process, the coordinator server respectively at subsequent points in time also function similarly. The client connects to the Internet via one of the gateways by referring to the GW address designated in the response from the server. A server which recognized that a failure has occurred in another server changes the GW address assigned to the client in order to switch the communication route for the client to access the Internet.

Abstract: A hemadynamometer has an air bag designed for attaining oppression or ischemia of radial artery only without oppressing ulnar artery, with a length of the bag made, when the bag is wound on a user's wrist on its radial side starting from such hard organization area as tendons on palm side of the wrist through the radial artery, to reach at least styloid process of radius but not to reach the ulnar artery, and with a width set for locally oppressing the radial artery at least substantially right above the styloid process of radius in longitudinal direction of the wrist.

Abstract: An improved portable battery powered therapy applicator which applies a high frequency electromagnetic field to a living tissue for promoting hematogenous effects. The applicator is in use to be attached to the skin of a patient and has a casing encapsulating therein, in addition to the battery, an antenna for directing the high electromagnetic field and electronic components forming an oscillator which energizes the antenna. These parts are mounted on a substrate which is made of a rigid material sufficient to resist deflection or deformation in order to protect the antenna on the substrate from deforming or receiving considerable stress at the time of detaching the applicator from the skin. Thus, the antenna can be kept free from breaking even through repeated operations of detaching the applicator, greatly enhancing reliability and prolong an operation life of the applicator.

Abstract: An automated blood pressure monitoring instrument including a noise level detector which enables the instrument to have the sound sensing performance analogous to the human ear. Sounds, including Korotkoff sounds, emitted from the occluded artery of a subject person are transduced into corresponding electric signals to be fed through a filter to the said noise level detector. At the noise level detector, a noise level is calculated from the incoming signals in such a manner as to exclude from this calculation values of expected Korotkoff sound levels and the like which are normally thought to be much higher than an estimated or assumed level of noises associated with the body in the normal blood pressure measurement. The noise level thus detected will vary depending upon the conditions of a subject person as well as varies from person to person, and therefore acts as an effective reference for identifying the Korotkoff sounds.

Abstract: A sphygmomanometer is provided with an automatic pressure inflation and deflation means for feeding a pressurized air into a cuff wound on the upper arm or the like so as to close the arterial blood flow. Korotkoff's sounds are detected during an interruption of the pressurized air feeding. The air is intermittently repressurized so long as the Korotkoff's sounds can be detected, and is switched over to an exhausting state when the Korotkoff's sounds are no longer detected. The systolic/diastolic blood pressure values are detected during the exhausting state and are digitally indicated. A continuous sound is generated until the Korotkoff's sounds reappear, and thereafter a sound is generated which is synchronized with Korotkoff's sounds.
