A protection apparatus is provided that can use a thermal fuse at higher voltage and higher current. The protection apparatus includes a protection circuit connected in series between a power supply and a load. The protection circuit includes a thermal fuse with a predetermined operating temperature, activated in response to sensing overheating of the power supply and/or load, and an electrosensitive fuse connected in parallel with the thermal fuse, and activated at a predetermined operating cur...

Ground surfaces are rendered impervious by first covering the ground with netting and then spraying glass fiber and polyester resin on the netting and allowing it to cure.

It is known in the art to place a low impedance path across the input circuit of an output amplifier when the power dissipation of the amplifier exceeds a given value. The present circuit includes, in addition, a gate controlled rectifier, the main conduction path of which is connected across the output terminals of the amplifier, and which is turned on in response to a flow of current through this low impedance path. This additional circuit protects the amplifier from voltage spikes produced, f...

A method for protecting at least one section of a program executed by a microcontroller, included before execution of the section, decrementing or incrementing at least one first counter and storing its state in a non-volatile memory of the microcontroller; in case of the detection of an attack attempt by the microcontroller, activating a flag in the microcontroller RAM; and at the end of the execution of the program section, checking the flag state.

Tampering with pieces of software is inhibited. Thread protection inhibits tampering with various threads that execute protective pieces of software. Profiles are stored in a central hierarchical database and such profiles are protected from tampering. The obfuscation of a software image so as to becloud the comprehension of hackers in reverse engineering pieces of software comprising the software image is provided.

An electric device generates a predetermined amount of heat in the event of a malfunction. The electric device is protected from overheating in that it is arranged, with a fuse in a circuit, such that the fuse and the electric device are thermally coupled to one another, so that the generation of the amount of heat by the electric device causes a material in the fuse to melt. In this manner, the current terminal path of the electric device is interrupted.

A method for the protection of trees of the families Musaceae or Plantanginaceae from destructive pests whereby the trees to be protected share a common root system.

A transparent canopy (7) covers an infant seated within a baby-buggy for protecting him/her from exposure to ambient-air pollution, and a powered filter-unit (9) blows filtered ambient-air into the top of the compartment (8) between the canopy (7) and the seat-unit (4). The bottom of the compartment (8) is open where a lower, apron portion (16) of the canopy (7) hangs spaced from the seated-infant's legs. Entry of polluted air via the opening is blocked by operating the powered filter-unit (9) t...

Responsive to a request for refrigeration, a start up sequence is initiated and, if start up is achieved, a number of motor and compressor parameters of operation are sensed for controlling and protecting the compressor. Depending upon the nature of the sensed conditions, if necessary, the motor, and thereby the compressor, is either disabled or corrective action is initially taken to bring the parameters within an acceptable range. If corrective action is ineffective, the motor and thereby the ...

The present invention features compositions and methods that are useful for storing labeled detection probes and detecting whether a target nucleic acid sequence is present in a sample. Preferred compositions are made up of a detection probe containing a label susceptible to a chemical or enzymatic alteration and a protection probe that protects the label from alteration and/or decreases the ability of the detection probe to inhibit nucleic acid amplification. Such compositions can be used, for ...
