Patent number: 8375431Abstract: A platform discrimination indication register is stored in a wireless network card. This register holds a platform discrimination indication that indicates whether the wireless network card can be used to transfer data with notebook computers or whether the wireless network card is restricted to transferring data from a personal digital assistant or defined set of restricted devices. The platform discrimination indication can be upgraded using a key value obtained from an Internet site. This key value is limited to a specific wireless network card because of the use of a unique electronic I.D. An Internet site encrypts the electronic I.D. to produce the first key, such as a platform activation key (PAK). This first key is then decrypted at the personal data device in order to obtain a unique calculated I.D. value. If the calculated I.D. value matches the electronic I.D.Type: GrantFiled: November 22, 2010Date of Patent: February 12, 2013Assignee: Sierra Wireless, Inc.Inventors: Richard Wodzianek, Jody Crowther, Iulian Mocanu, Kirstin Gulbransen

Publication number: 20130002503Abstract: An antenna and multi-antenna system are provided. Each antenna of the system is a mirror image and comprises first and second conductive elements each having a first end and a second end portion, the second end portions being capacitively coupled to each other. Each antenna can be operated as a lower-frequency folded dipole having a series capacitive gap which facilitates electrical lengthening of the antenna, or as a higher-frequency monopole antenna having a parasitic element which facilitates improved bandwidth. The antennas' feedpoints may be placed at opposite corners of a ground plane, and separated by a distance which is less than one quarter of an operating wavelength of the dipole but greater than one quarter of an operating wavelength of the monopole. Locating the feedpoints at the ground plane corners facilitates orthogonal polarization of the two antennas at least in dipole mode. The antennas thus provided exhibit good isolation.Type: ApplicationFiled: June 28, 2012Publication date: January 3, 2013Applicant: SIERRA WIRELESS, INC.Inventor: Mack Tan
