Abstract: In some embodiments, a method includes receiving, at a device, digital audio content to be converted by a digital-to-analog converter to produce analog audio content. The digital audio content has at least one audible frequency. The method also includes selecting, at the device, a first signal and a second signal to output with the analog audio content. The first signal has an inaudible carrier frequency and a bandwidth, and the second signal also has an inaudible carrier frequency and a bandwidth. A difference between the first signal and the second signal is an undesired audible signal. The method further includes outputting, from the device, the analog audio content, the first signal and the second signal, such that when the analog audio content is detected by a recording device the undesired audible signal is detected with the analog audio content.

Abstract: A method detects unauthorized access of data, and includes receiving data from a content provider by a content reproducing device; storing the received data in a memory storage device of the content reproducing device; obtaining an address range of a buffer of the content reproducing device; intercepting system application programming interface calls related to memory access of the address range of the buffer; comparing the intercepted system application programming interface calls to an expected sequence of memory access calls; and determining that a particular memory access call is unauthorized when the particular memory access call accesses the address range of the buffer while not belonging to the expected sequence of memory access calls.

Abstract: A method for securing intellectual property includes establishing contact between an IP server and a client. At least two component codes are shared and pre-stored in both the player and the server prior to ordering the intellectual property. The IP server accepts an order for an intellectual property product from the client. The IP server creates a shared private key based on the pre-stored shared component codes and an additional shared component code at the time the intellectual property product is ordered. The shared private key is not distributed to the player software. The IP server encrypts the intellectual property product with the created shared private key prior to distribution to the client. The intellectual property product further comprises content data and rights data in digital form. The IP server electronically distributes the intellectual property product to the client in encrypted form without the shared private key.

Abstract: A system and method for securing intellectual property rights in distributed intellectual property. Rights are granted and policed in electronically distributed intellectual property. Use limitations are established by agreement by the content provider and the client. The use limitations are reflected in time-based, usage-based and player based component codes that are used to determine if the client is entitled to use the intellectual property. Intellectual property is protected from unauthorized use by encrypting the intellectual property with a key created from some or all of the component codes. As the component codes are known to both the client and the content provider, no key exchange is required.

Abstract: This invention relates to an improved construction of finger and toe housing devices. It is adapted to be readily applied to the ends of fingers or toes for protecting injured and wounded areas.Still another aim of the invention is to improve and provide a housing construction that may be economically manufactured and sold to be worn in order to protect and enable the wearer to perform their duties in the home and office, requiring the use of the hands and legs during the recovery period.Still a further aim of the invention is to provide a strong protector of the class described of self-contained resilient molded bead-spine-hinged connected section having yieldable means of holding the sections in applied position with the built-in rear locking system 2 and 13, beyond the last joint of the finger or toe. Both sections 1 and 10 provide a convex apertured portion adapted to house the injured finger or toe during the recuperation period.

Abstract: Soot deposition from protective atmospheres and residual lubricants normally carried on ferrous wire and removed during annealing. During the cooling stage of an annealing cycle, air or other suitable oxygen containing gas is introduced into an annealing furnace containing the wire when the wire temperature is between approximately 1050.degree. and 950.degree. F. At these temperatures, the introduced oxygen is effective to volatilize the residual lubricant and soot formed from decomposition of carbon monoxide. This removal is accomplished without significant decarburization of the wire and only minor oxidation thereof. The oxygen containing gas may be introduced into a bell furnace by raising the inner cover thereof or the oxygen containing gas may be injected into the inner retort of a bell furnace or directly into a batch furnace.
