Some PDAs include Global Positioning System ( GPS ) receivers ; this is particularly true of smartphones.

Some cameras, GPS receivers and PDAs detect the safe end-of-discharge voltage of the series cells and auto-shutdown, but devices like flashlights and some toys do not.

Some modern designs even go as far as using GPS technology or heart-rate monitoring capabilities.

Some Pocket PCs feature integrated GPS often combined with mobile phone functionality.

Some examples of current Pocket PCs with GPS integrated are the Fujitsu Siemens Pocket Loox N560, a high-end Pocket PC with a VGA screen and an integrated SiRF Star III GPS ; the HTC TyTN ,< ref >

Some communities protect outdoor nativity scenes with surveillance cameras or GPS devices concealed within the figurines.

Some GPS receivers are integrated into autopilot or flight management system, to aid the pilot in control of an aircraft.

Some will also store positional GPS data during the flight for later analysis.

Some wireless carriers such as Nextel have decided GPS was the best way to provide the mandated location data for wireless Enhanced 9-1-1.

Personal two-way radios are also sometimes combined with other electronic devices ; Garmin's Rino series combine a GPS receiver in the same package as an FRS / GMRS walkie-talkie ( allowing Rino users to transmit digital location data to each other ) Some personal radios also include receivers for AM and FM broadcast radio and, where applicable, NOAA Weather Radio and similar systems broadcasting on the same frequencies.

Some GPS devices do not take into account the vertical position of the car so will under report the speed by the road's gradient.

Some GPS waypoints for the Drakensberg are listed below:

Some systems use GPS satellite receivers to obtain exact atomic time, for perfect synchronization with satellite-delivered programming.

; Vehicle tracking system: Some police vehicles, especially traffic units, may be fitted with equipment which will alert the officers to the presence nearby of a stolen vehicle fitted with a special transponder, and guide them towards it, using GPS or simpler radio triangulation

Some GPS enabled detectors can download the GPS coordinates of speed monitoring cameras and redlight cameras from the Internet, which are contained in the Trinity database.

Some can superimpose sonar and map data from GPS position.

Some aGPS devices do not have the option of falling back to standalone or autonomous GPS.

Some ads would include special offers in the form of vouchers or barcodes, and some would utilize the device's GPS system to direct users to the nearest store carrying the advertised product.

Some Electronic aids to navigation like Loran have already become obsolete themselves and have been replaced by GPS.

Some GPS watches can also be used as display.

Some communication links ( such as GPS transmissions, CDMA cell phones, and other spread spectrum links ) have a symbol rate much higher than the data rate ( they transmit many symbols called chips per data bit.

* Some systems ( but not all ) use continuous GPS tracking of vehicles, which a consumer may believe infringes on their privacy.

Some weapons systems have become obsolescent while still in production, and some while still under development.

Some phonetic features, for example glottal catch or murmur, are sometimes to be assigned to segmental phonemics and sometimes to accentual systems.

Some school systems provide written instructions to principals and teachers designating when certain information is to be recorded on cumulative record forms and explaining how the information is to be summarized and used.

Some US School districts and systems return to school in August.

Some belief systems, such as those in the Abrahamic tradition, hold that the dead go to a specific plane of existence after death, as determined by a god, gods, or other divine judgment, based on their actions or beliefs during life.

Some, like Hernando De Soto, argue that much of the poverty in the Third World countries is caused by the lack of Western systems of laws and well-defined and universally recognized property rights.

Some home sewage treatment systems use biological treatment, usually beds of plants and aquaria, that absorb nutrients and bacteria and convert greywater and sewage to clear water.

Some systems are vacuum-insulated, acting something like large thermos bottles.

Some proven intensive, low-effort food-production systems include urban gardening ( indoors and outdoors ).

Some systems used a CD-ROM drive to make the files available.

Some bicycle parts, particularly hub-based gearing systems, are complex, and many cyclists prefer to leave maintenance and repairs to professional bicycle mechanics.

Some systems have proposed as many as 90 subspecies, while recent DNA analysis has identified as few as five clades.

Some modern editing systems can use OCR techniques to read BITC in situations where other forms of timecode are not available.

Some linguists, such as John DeFrancis and J. Marshall Unger have argued that genuine ideographic writing systems with the same capacities as natural languages do not exist.

Some writing systems of the world, notably the Arabic and Hebrew scripts, and derived systems such as the Urdu, Persian, Yiddish, Jawi, and Ladino scripts, are written in a form known as right-to-left ( RTL ), in which writing begins at the right-hand side of a page and concludes at the left-hand side.

Some systems used both codes and ciphers in one system, using superencipherment to increase the security.

Some take the approach of looking for coherent justifications of established copyright systems, while others start with general ethical theories, such as utilitarianism and try to analyse policy through that lens.

Some critics of this approach feel that while these models approach biological reality as a representation of how the system works, they lack explanatory powers because complicated systems of connections with even simple rules are extremely complex and often less interpretable than the system they model.

Some jurisdictions give priority to motorized traffic, for example setting up one-way street systems, free-right turns, high capacity roundabouts, and slip roads.

Some masters use different systems, or even no system at all.

Some light rail systems may run on a narrower gauge.

Some missiles can be fitted with any of a variety of navigation systems ( Inertial navigation, TERCOM, or satellite navigation ).

Some GC systems allow such other resources to be associated with a region of memory that, when collected, causes the other resource to be reclaimed ; this is called finalization.

Some, like VirtualBox and VMware Player run on Windows and Linux hosts and can run many other operating systems.
