Sep 30, 1997

Appl. No.:

08/941408

Inventors:

Andrew M. Goldstein - Newton MA

Assignee:

The Holmes Group, Inc. - Milford MA

International Classification:

H05B 300

US Classification:

392367, 392368, D23335

Abstract:

A positive temperature coefficient (PTC) heater includes a housing, a fan mounted within the housing, a pair of positive temperature coefficient (PTC) heater assemblies disposed in the housing, and a plenum mounted in the housing. The housing includes a front portion and a rear portion connected together to define a front, a rear, a left side and a right side, the front and rear each having at least one opening. The fan is arranged to produce a flow of air from the rear of the housing to the front. The pair of positive temperature coefficient (PTC) heater assemblies are disposed in side by side relationship and angled relative to each other, each at an angle of approximately 7. 5 degrees from normal, so as to produce a diverging column of heated air. The plenum mounted in the housing directs the air flow produced by the fan through each of the PTC heater assemblies.

International Classification:

G06F 1100

US Classification:

714 20

Abstract:

A backup apparatus and method suitable for protecting the data volume in a computer system function by acquiring a base state snapshot and a sequential series of data volume snapshots, the apparatus concurrently generating succedent and precedent lists of snapshot differences which are used to create succedent and precedent backups respectively. The data volume is restored by overwriting the base state data with data blocks identified in one or more succedent backups. File recovery is accomplished by overwriting data from a current snapshot with one or more precedent backups.

Abstract:

In accordance with at least some embodiments of the invention, a system comprises a plurality of computers coupled together and to an array of redundant storage devices that is accessible to the plurality of computers. Each of the plurality of computers comprises a local memory that stores at least one bitmap. The least one bitmap logs regions of the redundant array that have been modified.

Inventors:

John Andruszkiewicz - Hollis NH, US
Andrew Goldstein - Hudson MA, US

International Classification:

G06F 12/16

US Classification:

711162000

Abstract:

A first computer is adapted to communicate with another computer and to a redundant storage subsystem external to the first computer. The first computer comprises memory comprising state information and a processor that receives a state from another computer. The received state is indicative of whether the other computer may perform write transactions to the redundant storage subsystem. The first computer's processor also determines whether to perform a data merge operation on the redundant storage subsystem based on the other computer's last received state prior to a failure of the other computer.

Assignee:

Holmes Products Corp. - Milford MA

International Classification:

F01D 700

US Classification:

416100

Abstract:

A window mounted oscillating fan. The fan has two blower modules each having a motor, fan blade, and diffuser. The diffuser is fixed in a stationary position relative to its fan blade. The window fan oscillates by pivoting all blower modules simultaneously through a single motorized oscillation mechanism. The blower units may be arranged to discharge air in parallel, or alternatively, in different directions. The blower units pivot about an axis inclined from the vertical, so that oscillation has a vertical component as well as horizontal. In different embodiments, the fans operate in tandem, facing the same direction at all times, or oscillate in different directions, thereby diffusing incoming air. The window fan has an air filter, and manual and automatic controls including a touch sensitive on-off switch, a thermostatic on-off switch, and a speed selector.

Abstract:

A method for denying a first group access to a system resource wherein a second group is selected such that the first group is a subgroup of the second group. Access is granted only to those members of the second group who do not derive their membership in the second group through their membership in the first group.

International Classification:

US Classification:

392367

Abstract:

A portable forced air space heater having a three hundred sixty degree peripheral dispersion pattern. The heater has a tubular housing and a fan forcing air past a heating element upwardly within the housing. The air encounters a conical deflector which redirects the air to flow outwardly at the top of the housing. One or more movable baffles are selectively placed in the housing so as to obstruct discharge of air at various selected sections of the peripheral pattern of discharge. This feature prevents injurious or otherwise objectionable discharge of heat when the heater is placed close to another object. The baffles are arcuate, so that they cooperate with the tubular housing, and insulated to minimize propogation of heat to the obstructed portion of the discharge pattern. Baffles are removable from the heater, and are maneuvered for adjusting their position from outside the heater.
