Abstract: Systems, methods, and apparatus to identify media devices are disclosed. An example apparatus includes a listing retriever to retrieve a list of device names corresponding to devices identified as present on a local area network, the list of device names retrieved from a network activity measurement system located outside of the local area network. The example apparatus includes a communications analyzer to identify a list of hardware addresses of devices on the local area network. The example apparatus includes a mapper to receive a mapping between a device in the list of devices and a hardware address in the hardware addresses. The mapper is to transmit the mapping to the network activity measurement system.

Abstract: Methods and apparatus to use scent to collect audience information are disclosed. An example apparatus includes a media meter to collect media identification information to identify media presented by an information presentation device; a people meter to identify a person in an audience of the information presentation device. The people meter includes a scent detector to detect a first scent of the person; a scent database containing a set of reference scents; a scent comparer to determine a first likelihood that the person corresponds to a first panelist identifier by comparing the first scent to at least some of the reference scents in the set; and identification logic to identify the person as corresponding to the first panelist identifier based on the first likelihood.

Abstract: A key duplicating machine having a key clamping assembly for supporting a key blank and a customer key to be duplicated, a key cutter assembly having a cutter wheel for cutting a pattern on the supported key blank and a follower for tracing a tooth patter on the supported customer key, a housing having a front wall, a top wall and a chip collection drawer lcoated below the front and top walls, the key clamping assembly being mounted on the front wall and the key cutter assembly being mounted on the top wall such that no obstructions exist between the key cutter assembly and the chip collection drawer located below the top wall, so that chips formed from a key cutting operation by the key cutter assembly fall unimpeded to the chip collection drawer, and surfaces which may collect the chips are minimized.

Abstract: A key duplicating machine which automatically liens the original and blank keys, clamping the keys in alignment with the appropriate clamping pressure, cuts double-sided keys in a single pass, prevents operation of the machine without the presence of the original and blank keys in the machine and which is capable of accepting virtually any type of key shape for duplication. The invention includes a single-sided key duplicating module having a motor driven cutter wheel which is slidably mounted on a travel table that, in turn, is slidably mounted on a base plate. The travel table includes a motor driven stacked cam assembly which engages fixed cam followers in the base plate, so when rotated, the cam assembly, travel table and cutter wheels are moved first in a cutting pass, then in a return pass with respect to the original and blank keys. The cam assembly also includes a cam follower which displaces the cutting wheel sidewardly away from the blank key on the return pass.
