Systems and methods described herein provide for novel configuration features for setting up a user device automatically to connect to a network and register the user device to a user account. A mapping of user devices to cryptographic keys for the user devices may be maintained by a computer system. The computer system may receive information that specifies network information and user account information for a particular user device. A mapping of the network information and user account information to the particular user device may be generated. A machine-readable code that includes the network information for connecting the particular user device to the network and a token that includes credentials for the user account information may be generated and transmitted to a assistant configuration device.

A guide rod extends longitudinally through the power piston of a vacuum power booster providing lateral support thereto and tying the master cylinder housing to a bracket on the rear of the power booster housing. A guide rod provides a means of positively laterally supporting the power piston, control valve and push rods of the power booster thereby providing the ability to reduce the relative supportive strength of the housing, housing divider and piston bearings.

An electric lawn mower and power cord combination in which the power cord has a central portion that is self-coiling. This central portion of the cord comprises the predominant length of the cord, and is constructed with an elastic memory, so that, when in its relaxed state, it automatically coils itself into a continuous spiralling helix that is too large to pass under the electric lawn mower. A cord grip is also disclosed that locks the cord to a stationary object to prevent the cord from inadvertently becoming disconnected during use.

Apparatus for directly measuring the quantity .sqroot..rho.ck of a test specimen such as a wind tunnel model where .rho. is the density, c is the specific heat and k is the thermal conductivity of the specimen. The test specimen and a reference specimen are simultaneously subjected to the heat from a heat source. A thermocouple is attached to the reference specimen for producing a first electrical analog signal proportional to the heat rate Q that the test specimen is subjected to and an infrared radiometer that is aimed at the test specimen produces a second electrical analog signal proportional to the surface temperature T of the test specimen. An analog-to-digital converter converts the first and second electrical analog signals to digital signals. These digital signals are applied to a computer for determining the quantity .sqroot..rho.ck by computing the quantity ##EQU1## WHERE T.sub.i is the initial test specimen temperature and t is the elapsed time from the time that the specimens were first subjected to the heat source.
